Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678140, here are decompositions:
- 11 + 8678129 = 8678140
- 47 + 8678093 = 8678140
- 59 + 8678081 = 8678140
- 71 + 8678069 = 8678140
- 83 + 8678057 = 8678140
- 89 + 8678051 = 8678140
- 101 + 8678039 = 8678140
- 113 + 8678027 = 8678140
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 8,678,140 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
