Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102564, here are decompositions:

  • 5 + 102559 = 102564
  • 13 + 102551 = 102564
  • 17 + 102547 = 102564
  • 31 + 102533 = 102564
  • 41 + 102523 = 102564
  • 61 + 102503 = 102564
  • 67 + 102497 = 102564
  • 83 + 102481 = 102564

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 102,564 and was likely granted around 1870.

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