Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104640, here are decompositions:
- 17 + 104623 = 104640
- 43 + 104597 = 104640
- 47 + 104593 = 104640
- 61 + 104579 = 104640
- 79 + 104561 = 104640
- 89 + 104551 = 104640
- 97 + 104543 = 104640
- 103 + 104537 = 104640
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.152.192.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 104.640 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
