Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671550, here are decompositions:
- 31 + 8671519 = 8671550
- 79 + 8671471 = 8671550
- 103 + 8671447 = 8671550
- 109 + 8671441 = 8671550
- 157 + 8671393 = 8671550
- 211 + 8671339 = 8671550
- 229 + 8671321 = 8671550
- 331 + 8671219 = 8671550
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 8,671,550 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
