Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 960640, here are decompositions:
- 3 + 960637 = 960640
- 47 + 960593 = 960640
- 53 + 960587 = 960640
- 59 + 960581 = 960640
- 71 + 960569 = 960640
- 113 + 960527 = 960640
- 173 + 960467 = 960640
- 251 + 960389 = 960640
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 960,640 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
