Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540722, here are decompositions:
- 13 + 31540709 = 31540722
- 23 + 31540699 = 31540722
- 29 + 31540693 = 31540722
- 43 + 31540679 = 31540722
- 53 + 31540669 = 31540722
- 71 + 31540651 = 31540722
- 79 + 31540643 = 31540722
- 149 + 31540573 = 31540722
Showing the first eight; more decompositions exist.
