Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156584, here are decompositions:

  • 7 + 156577 = 156584
  • 73 + 156511 = 156584
  • 97 + 156487 = 156584
  • 163 + 156421 = 156584
  • 223 + 156361 = 156584
  • 277 + 156307 = 156584
  • 331 + 156253 = 156584
  • 367 + 156217 = 156584

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 156,584 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 156584 first appears in π at position 167,743 of the decimal expansion (the 167,743ordinal-suffix:rd 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.
