Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488032, here are decompositions:
- 13 + 31488019 = 31488032
- 19 + 31488013 = 31488032
- 229 + 31487803 = 31488032
- 613 + 31487419 = 31488032
- 769 + 31487263 = 31488032
- 1033 + 31486999 = 31488032
- 1051 + 31486981 = 31488032
- 1321 + 31486711 = 31488032
Showing the first eight; more decompositions exist.
