Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002564, here are decompositions:
- 11 + 1002553 = 1002564
- 37 + 1002527 = 1002564
- 41 + 1002523 = 1002564
- 47 + 1002517 = 1002564
- 53 + 1002511 = 1002564
- 61 + 1002503 = 1002564
- 71 + 1002493 = 1002564
- 83 + 1002481 = 1002564
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 1,002,564 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
