Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529652, here are decompositions:
- 23 + 31529629 = 31529652
- 29 + 31529623 = 31529652
- 59 + 31529593 = 31529652
- 101 + 31529551 = 31529652
- 113 + 31529539 = 31529652
- 131 + 31529521 = 31529652
- 173 + 31529479 = 31529652
- 181 + 31529471 = 31529652
Showing the first eight; more decompositions exist.
