Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157726, here are decompositions:

  • 5 + 157721 = 157726
  • 47 + 157679 = 157726
  • 59 + 157667 = 157726
  • 89 + 157637 = 157726
  • 167 + 157559 = 157726
  • 269 + 157457 = 157726
  • 293 + 157433 = 157726
  • 419 + 157307 = 157726

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 157,726 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 157726 first appears in π at position 177,330 of the decimal expansion (the 177,330ordinal-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.
