Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700624, here are decompositions:
- 43 + 8700581 = 8700624
- 61 + 8700563 = 8700624
- 103 + 8700521 = 8700624
- 113 + 8700511 = 8700624
- 151 + 8700473 = 8700624
- 157 + 8700467 = 8700624
- 167 + 8700457 = 8700624
- 193 + 8700431 = 8700624
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 8,700,624 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
