Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115418, here are decompositions:

  • 19 + 115399 = 115418
  • 97 + 115321 = 115418
  • 109 + 115309 = 115418
  • 139 + 115279 = 115418
  • 181 + 115237 = 115418
  • 397 + 115021 = 115418
  • 421 + 114997 = 115418
  • 571 + 114847 = 115418

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 115,418 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 115418 first appears in π at position 635,187 of the decimal expansion (the 635,187ordinal-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.
