Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671522, here are decompositions:
- 3 + 8671519 = 8671522
- 5 + 8671517 = 8671522
- 11 + 8671511 = 8671522
- 23 + 8671499 = 8671522
- 53 + 8671469 = 8671522
- 59 + 8671463 = 8671522
- 113 + 8671409 = 8671522
- 191 + 8671331 = 8671522
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 8,671,522 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
