Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541724, here are decompositions:
- 17 + 31541707 = 31541724
- 31 + 31541693 = 31541724
- 47 + 31541677 = 31541724
- 73 + 31541651 = 31541724
- 113 + 31541611 = 31541724
- 127 + 31541597 = 31541724
- 167 + 31541557 = 31541724
- 197 + 31541527 = 31541724
Showing the first eight; more decompositions exist.
