Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942440, here are decompositions:

  • 3 + 942437 = 942440
  • 7 + 942433 = 942440
  • 73 + 942367 = 942440
  • 127 + 942313 = 942440
  • 139 + 942301 = 942440
  • 193 + 942247 = 942440
  • 223 + 942217 = 942440
  • 241 + 942199 = 942440

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 942,440 and was likely granted around 1909.

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

Position in π

The digit sequence 942440 first appears in π at position 27,908 of the decimal expansion (the 27,908ordinal-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.
