Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540752, here are decompositions:
- 29 + 31540723 = 31540752
- 43 + 31540709 = 31540752
- 53 + 31540699 = 31540752
- 59 + 31540693 = 31540752
- 73 + 31540679 = 31540752
- 83 + 31540669 = 31540752
- 101 + 31540651 = 31540752
- 109 + 31540643 = 31540752
Showing the first eight; more decompositions exist.
