Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559822, here are decompositions:
- 13 + 31559809 = 31559822
- 103 + 31559719 = 31559822
- 163 + 31559659 = 31559822
- 181 + 31559641 = 31559822
- 199 + 31559623 = 31559822
- 379 + 31559443 = 31559822
- 409 + 31559413 = 31559822
- 421 + 31559401 = 31559822
Showing the first eight; more decompositions exist.
