Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662140, here are decompositions:
- 7 + 8662133 = 8662140
- 13 + 8662127 = 8662140
- 31 + 8662109 = 8662140
- 61 + 8662079 = 8662140
- 83 + 8662057 = 8662140
- 103 + 8662037 = 8662140
- 131 + 8662009 = 8662140
- 163 + 8661977 = 8662140
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 8,662,140 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
