Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475712, here are decompositions:
- 29 + 31475683 = 31475712
- 31 + 31475681 = 31475712
- 43 + 31475669 = 31475712
- 89 + 31475623 = 31475712
- 101 + 31475611 = 31475712
- 113 + 31475599 = 31475712
- 131 + 31475581 = 31475712
- 223 + 31475489 = 31475712
Showing the first eight; more decompositions exist.
