Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708040, here are decompositions:
- 23 + 8708017 = 8708040
- 37 + 8708003 = 8708040
- 41 + 8707999 = 8708040
- 43 + 8707997 = 8708040
- 71 + 8707969 = 8708040
- 101 + 8707939 = 8708040
- 137 + 8707903 = 8708040
- 157 + 8707883 = 8708040
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 8,708,040 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
