Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999626, here are decompositions:

  • 3 + 999623 = 999626
  • 13 + 999613 = 999626
  • 73 + 999553 = 999626
  • 97 + 999529 = 999626
  • 127 + 999499 = 999626
  • 193 + 999433 = 999626
  • 409 + 999217 = 999626
  • 457 + 999169 = 999626

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 999,626 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 999626 first appears in π at position 115,684 of the decimal expansion (the 115,684ordinal-suffix:th 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.
