Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505156, here are decompositions:

  • 17 + 505139 = 505156
  • 59 + 505097 = 505156
  • 83 + 505073 = 505156
  • 89 + 505067 = 505156
  • 107 + 505049 = 505156
  • 167 + 504989 = 505156
  • 173 + 504983 = 505156
  • 227 + 504929 = 505156

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 505,156 and was likely granted around 1893.

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

Position in π

The digit sequence 505156 first appears in π at position 627,632 of the decimal expansion (the 627,632ordinal-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.
