Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523730, here are decompositions:
- 23 + 31523707 = 31523730
- 61 + 31523669 = 31523730
- 71 + 31523659 = 31523730
- 79 + 31523651 = 31523730
- 83 + 31523647 = 31523730
- 97 + 31523633 = 31523730
- 131 + 31523599 = 31523730
- 151 + 31523579 = 31523730
Showing the first eight; more decompositions exist.
