Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543470, here are decompositions:
- 17 + 31543453 = 31543470
- 19 + 31543451 = 31543470
- 41 + 31543429 = 31543470
- 73 + 31543397 = 31543470
- 109 + 31543361 = 31543470
- 139 + 31543331 = 31543470
- 197 + 31543273 = 31543470
- 227 + 31543243 = 31543470
Showing the first eight; more decompositions exist.
