Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127522, here are decompositions:

  • 29 + 127493 = 127522
  • 41 + 127481 = 127522
  • 149 + 127373 = 127522
  • 179 + 127343 = 127522
  • 191 + 127331 = 127522
  • 233 + 127289 = 127522
  • 251 + 127271 = 127522
  • 281 + 127241 = 127522

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 127,522 and was likely granted around 1872.

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

Position in π

The digit sequence 127522 first appears in π at position 716,677 of the decimal expansion (the 716,677ordinal-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.
