Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536240, here are decompositions:
- 13 + 31536227 = 31536240
- 17 + 31536223 = 31536240
- 37 + 31536203 = 31536240
- 53 + 31536187 = 31536240
- 79 + 31536161 = 31536240
- 139 + 31536101 = 31536240
- 179 + 31536061 = 31536240
- 191 + 31536049 = 31536240
Showing the first eight; more decompositions exist.
