Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012440, here are decompositions:
- 7 + 1012433 = 1012440
- 17 + 1012423 = 1012440
- 19 + 1012421 = 1012440
- 29 + 1012411 = 1012440
- 41 + 1012399 = 1012440
- 43 + 1012397 = 1012440
- 61 + 1012379 = 1012440
- 67 + 1012373 = 1012440
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 1,012,440 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
