Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532610, here are decompositions:
- 13 + 31532597 = 31532610
- 17 + 31532593 = 31532610
- 23 + 31532587 = 31532610
- 29 + 31532581 = 31532610
- 37 + 31532573 = 31532610
- 59 + 31532551 = 31532610
- 71 + 31532539 = 31532610
- 89 + 31532521 = 31532610
Showing the first eight; more decompositions exist.
