Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540726, here are decompositions:
- 3 + 31540723 = 31540726
- 17 + 31540709 = 31540726
- 47 + 31540679 = 31540726
- 83 + 31540643 = 31540726
- 89 + 31540637 = 31540726
- 197 + 31540529 = 31540726
- 227 + 31540499 = 31540726
- 233 + 31540493 = 31540726
Showing the first eight; more decompositions exist.
