Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672842, here are decompositions:
- 11 + 8672831 = 8672842
- 23 + 8672819 = 8672842
- 41 + 8672801 = 8672842
- 53 + 8672789 = 8672842
- 281 + 8672561 = 8672842
- 359 + 8672483 = 8672842
- 401 + 8672441 = 8672842
- 419 + 8672423 = 8672842
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 8,672,842 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
