Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578890, here are decompositions:

  • 29 + 578861 = 578890
  • 47 + 578843 = 578890
  • 71 + 578819 = 578890
  • 101 + 578789 = 578890
  • 113 + 578777 = 578890
  • 149 + 578741 = 578890
  • 197 + 578693 = 578890
  • 269 + 578621 = 578890

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 578,890 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 578890 first appears in π at position 251,422 of the decimal expansion (the 251,422ordinal-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.
