Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002456, here are decompositions:
- 5 + 1002451 = 1002456
- 23 + 1002433 = 1002456
- 29 + 1002427 = 1002456
- 53 + 1002403 = 1002456
- 79 + 1002377 = 1002456
- 97 + 1002359 = 1002456
- 107 + 1002349 = 1002456
- 109 + 1002347 = 1002456
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 1,002,456 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
