Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115040, here are decompositions:
- 19 + 115021 = 115040
- 43 + 114997 = 115040
- 67 + 114973 = 115040
- 73 + 114967 = 115040
- 127 + 114913 = 115040
- 139 + 114901 = 115040
- 151 + 114889 = 115040
- 157 + 114883 = 115040
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 115,040 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
