Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667438, here are decompositions:
- 7 + 8667431 = 8667438
- 11 + 8667427 = 8667438
- 19 + 8667419 = 8667438
- 61 + 8667377 = 8667438
- 67 + 8667371 = 8667438
- 89 + 8667349 = 8667438
- 137 + 8667301 = 8667438
- 139 + 8667299 = 8667438
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 8,667,438 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
