Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121574, here are decompositions:

  • 3 + 121571 = 121574
  • 43 + 121531 = 121574
  • 67 + 121507 = 121574
  • 73 + 121501 = 121574
  • 127 + 121447 = 121574
  • 223 + 121351 = 121574
  • 241 + 121333 = 121574
  • 283 + 121291 = 121574

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 121,574 and was likely granted around 1871.

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

Position in π

The digit sequence 121574 first appears in π at position 347,601 of the decimal expansion (the 347,601ordinal-suffix:st 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.
