Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672428, here are decompositions:
- 5 + 8672423 = 8672428
- 41 + 8672387 = 8672428
- 47 + 8672381 = 8672428
- 131 + 8672297 = 8672428
- 227 + 8672201 = 8672428
- 251 + 8672177 = 8672428
- 311 + 8672117 = 8672428
- 449 + 8671979 = 8672428
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 8,672,428 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
