Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673872, here are decompositions:
- 271 + 8673601 = 8673872
- 373 + 8673499 = 8673872
- 409 + 8673463 = 8673872
- 439 + 8673433 = 8673872
- 499 + 8673373 = 8673872
- 601 + 8673271 = 8673872
- 673 + 8673199 = 8673872
- 751 + 8673121 = 8673872
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 8,673,872 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
