Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543704, here are decompositions:
- 7 + 31543697 = 31543704
- 13 + 31543691 = 31543704
- 43 + 31543661 = 31543704
- 61 + 31543643 = 31543704
- 173 + 31543531 = 31543704
- 223 + 31543481 = 31543704
- 251 + 31543453 = 31543704
- 307 + 31543397 = 31543704
Showing the first eight; more decompositions exist.
