Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541748, here are decompositions:
- 11 + 31541737 = 31541748
- 41 + 31541707 = 31541748
- 71 + 31541677 = 31541748
- 89 + 31541659 = 31541748
- 97 + 31541651 = 31541748
- 137 + 31541611 = 31541748
- 151 + 31541597 = 31541748
- 157 + 31541591 = 31541748
Showing the first eight; more decompositions exist.
