Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008740, here are decompositions:

  • 127 + 1008613 = 1008740
  • 151 + 1008589 = 1008740
  • 193 + 1008547 = 1008740
  • 199 + 1008541 = 1008740
  • 223 + 1008517 = 1008740
  • 241 + 1008499 = 1008740
  • 307 + 1008433 = 1008740
  • 331 + 1008409 = 1008740

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,008,740 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1008740 first appears in π at position 615,961 of the decimal expansion (the 615,961ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
