Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128594, here are decompositions:

  • 3 + 128591 = 128594
  • 31 + 128563 = 128594
  • 43 + 128551 = 128594
  • 73 + 128521 = 128594
  • 127 + 128467 = 128594
  • 157 + 128437 = 128594
  • 163 + 128431 = 128594
  • 181 + 128413 = 128594

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 128,594 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 128594 first appears in π at position 932,323 of the decimal expansion (the 932,323ordinal-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.
