Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115278, here are decompositions:

  • 19 + 115259 = 115278
  • 29 + 115249 = 115278
  • 41 + 115237 = 115278
  • 67 + 115211 = 115278
  • 127 + 115151 = 115278
  • 151 + 115127 = 115278
  • 179 + 115099 = 115278
  • 199 + 115079 = 115278

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 115,278 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 115278 first appears in π at position 460,856 of the decimal expansion (the 460,856ordinal-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.
