Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185738, here are decompositions:
- 31 + 185707 = 185738
- 61 + 185677 = 185738
- 97 + 185641 = 185738
- 139 + 185599 = 185738
- 181 + 185557 = 185738
- 199 + 185539 = 185738
- 211 + 185527 = 185738
- 271 + 185467 = 185738
Showing the first eight; more decompositions exist.
