Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112778, here are decompositions:

  • 7 + 112771 = 112778
  • 19 + 112759 = 112778
  • 37 + 112741 = 112778
  • 157 + 112621 = 112778
  • 271 + 112507 = 112778
  • 277 + 112501 = 112778
  • 349 + 112429 = 112778
  • 439 + 112339 = 112778

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 112,778 and was likely granted around 1871.

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

Position in π

The digit sequence 112778 first appears in π at position 460,192 of the decimal expansion (the 460,192ordinal-suffix:nd 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.
