Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672378, here are decompositions:
- 31 + 8672347 = 8672378
- 139 + 8672239 = 8672378
- 277 + 8672101 = 8672378
- 331 + 8672047 = 8672378
- 397 + 8671981 = 8672378
- 541 + 8671837 = 8672378
- 709 + 8671669 = 8672378
- 739 + 8671639 = 8672378
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 8,672,378 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
