Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672400, here are decompositions:
- 13 + 8672387 = 8672400
- 19 + 8672381 = 8672400
- 47 + 8672353 = 8672400
- 53 + 8672347 = 8672400
- 67 + 8672333 = 8672400
- 103 + 8672297 = 8672400
- 127 + 8672273 = 8672400
- 137 + 8672263 = 8672400
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 8,672,400 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
