Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002642, here are decompositions:
- 19 + 1002623 = 1002642
- 23 + 1002619 = 1002642
- 59 + 1002583 = 1002642
- 73 + 1002569 = 1002642
- 89 + 1002553 = 1002642
- 131 + 1002511 = 1002642
- 139 + 1002503 = 1002642
- 149 + 1002493 = 1002642
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 1,002,642 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
