Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532682, here are decompositions:
- 23 + 31532659 = 31532682
- 29 + 31532653 = 31532682
- 43 + 31532639 = 31532682
- 89 + 31532593 = 31532682
- 101 + 31532581 = 31532682
- 109 + 31532573 = 31532682
- 131 + 31532551 = 31532682
- 193 + 31532489 = 31532682
Showing the first eight; more decompositions exist.
