Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700120, here are decompositions:
- 7 + 8700113 = 8700120
- 41 + 8700079 = 8700120
- 61 + 8700059 = 8700120
- 73 + 8700047 = 8700120
- 83 + 8700037 = 8700120
- 89 + 8700031 = 8700120
- 101 + 8700019 = 8700120
- 109 + 8700011 = 8700120
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 8,700,120 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
