Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031240, here are decompositions:
- 79 + 1031161 = 1031240
- 103 + 1031137 = 1031240
- 193 + 1031047 = 1031240
- 283 + 1030957 = 1031240
- 307 + 1030933 = 1031240
- 367 + 1030873 = 1031240
- 373 + 1030867 = 1031240
- 409 + 1030831 = 1031240
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 1,031,240 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
