Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004640, here are decompositions:
- 41 + 1004599 = 1004640
- 73 + 1004567 = 1004640
- 79 + 1004561 = 1004640
- 89 + 1004551 = 1004640
- 103 + 1004537 = 1004640
- 113 + 1004527 = 1004640
- 139 + 1004501 = 1004640
- 157 + 1004483 = 1004640
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 1,004,640 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
