Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156824, here are decompositions:

  • 7 + 156817 = 156824
  • 43 + 156781 = 156824
  • 97 + 156727 = 156824
  • 193 + 156631 = 156824
  • 223 + 156601 = 156824
  • 313 + 156511 = 156824
  • 331 + 156493 = 156824
  • 337 + 156487 = 156824

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 156,824 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 156824 first appears in π at position 618,209 of the decimal expansion (the 618,209ordinal-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.
