Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672040, here are decompositions:
- 37 + 8672003 = 8672040
- 53 + 8671987 = 8672040
- 59 + 8671981 = 8672040
- 61 + 8671979 = 8672040
- 73 + 8671967 = 8672040
- 103 + 8671937 = 8672040
- 229 + 8671811 = 8672040
- 271 + 8671769 = 8672040
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 8,672,040 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
