Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174240, here are decompositions:

  • 19 + 174221 = 174240
  • 43 + 174197 = 174240
  • 71 + 174169 = 174240
  • 83 + 174157 = 174240
  • 97 + 174143 = 174240
  • 103 + 174137 = 174240
  • 139 + 174101 = 174240
  • 149 + 174091 = 174240

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 174,240 and was likely granted around 1874.

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

Position in π

The digit sequence 174240 first appears in π at position 469,192 of the decimal expansion (the 469,192ordinal-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.
