Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155276, here are decompositions:

  • 7 + 155269 = 155276
  • 67 + 155209 = 155276
  • 73 + 155203 = 155276
  • 109 + 155167 = 155276
  • 139 + 155137 = 155276
  • 157 + 155119 = 155276
  • 193 + 155083 = 155276
  • 229 + 155047 = 155276

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 155,276 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 155276 first appears in π at position 911,037 of the decimal expansion (the 911,037ordinal-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.
