Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670642, here are decompositions:
- 5 + 8670637 = 8670642
- 23 + 8670619 = 8670642
- 31 + 8670611 = 8670642
- 53 + 8670589 = 8670642
- 59 + 8670583 = 8670642
- 83 + 8670559 = 8670642
- 89 + 8670553 = 8670642
- 109 + 8670533 = 8670642
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 8,670,642 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
