Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155364, here are decompositions:

  • 31 + 155333 = 155364
  • 37 + 155327 = 155364
  • 47 + 155317 = 155364
  • 61 + 155303 = 155364
  • 73 + 155291 = 155364
  • 113 + 155251 = 155364
  • 163 + 155201 = 155364
  • 173 + 155191 = 155364

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 155,364 and was likely granted around 1873.

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

Position in π

The digit sequence 155364 first appears in π at position 349,246 of the decimal expansion (the 349,246ordinal-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.
