Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115664, here are decompositions:

  • 7 + 115657 = 115664
  • 61 + 115603 = 115664
  • 67 + 115597 = 115664
  • 103 + 115561 = 115664
  • 151 + 115513 = 115664
  • 193 + 115471 = 115664
  • 337 + 115327 = 115664
  • 463 + 115201 = 115664

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 115,664 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 115664 first appears in π at position 178,892 of the decimal expansion (the 178,892ordinal-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.
