Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540674, here are decompositions:
- 5 + 31540669 = 31540674
- 17 + 31540657 = 31540674
- 23 + 31540651 = 31540674
- 31 + 31540643 = 31540674
- 37 + 31540637 = 31540674
- 43 + 31540631 = 31540674
- 101 + 31540573 = 31540674
- 173 + 31540501 = 31540674
Showing the first eight; more decompositions exist.
