Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532652, here are decompositions:
- 13 + 31532639 = 31532652
- 59 + 31532593 = 31532652
- 71 + 31532581 = 31532652
- 79 + 31532573 = 31532652
- 101 + 31532551 = 31532652
- 113 + 31532539 = 31532652
- 131 + 31532521 = 31532652
- 163 + 31532489 = 31532652
Showing the first eight; more decompositions exist.
