Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578788, here are decompositions:

  • 11 + 578777 = 578788
  • 47 + 578741 = 578788
  • 59 + 578729 = 578788
  • 101 + 578687 = 578788
  • 167 + 578621 = 578788
  • 179 + 578609 = 578788
  • 191 + 578597 = 578788
  • 251 + 578537 = 578788

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 578,788 and was likely granted around 1896.

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

Position in π

The digit sequence 578788 first appears in π at position 690,852 of the decimal expansion (the 690,852ordinal-suffix:nd 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.
