Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155056, here are decompositions:

  • 29 + 155027 = 155056
  • 47 + 155009 = 155056
  • 53 + 155003 = 155056
  • 113 + 154943 = 155056
  • 173 + 154883 = 155056
  • 179 + 154877 = 155056
  • 233 + 154823 = 155056
  • 257 + 154799 = 155056

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 155,056 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 155056 first appears in π at position 501,068 of the decimal expansion (the 501,068ordinal-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.
