Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543652, here are decompositions:
- 73 + 31543579 = 31543652
- 109 + 31543543 = 31543652
- 163 + 31543489 = 31543652
- 199 + 31543453 = 31543652
- 223 + 31543429 = 31543652
- 379 + 31543273 = 31543652
- 409 + 31543243 = 31543652
- 421 + 31543231 = 31543652
Showing the first eight; more decompositions exist.
