Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563932, here are decompositions:
- 3 + 31563929 = 31563932
- 61 + 31563871 = 31563932
- 139 + 31563793 = 31563932
- 199 + 31563733 = 31563932
- 331 + 31563601 = 31563932
- 541 + 31563391 = 31563932
- 739 + 31563193 = 31563932
- 769 + 31563163 = 31563932
Showing the first eight; more decompositions exist.
