Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512664, here are decompositions:
- 7 + 512657 = 512664
- 23 + 512641 = 512664
- 43 + 512621 = 512664
- 67 + 512597 = 512664
- 71 + 512593 = 512664
- 73 + 512591 = 512664
- 83 + 512581 = 512664
- 127 + 512537 = 512664
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 512,664 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
