Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005624, here are decompositions:
- 5 + 1005619 = 1005624
- 7 + 1005617 = 1005624
- 31 + 1005593 = 1005624
- 43 + 1005581 = 1005624
- 71 + 1005553 = 1005624
- 73 + 1005551 = 1005624
- 83 + 1005541 = 1005624
- 97 + 1005527 = 1005624
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 1,005,624 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
