Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532732, here are decompositions:
- 73 + 31532659 = 31532732
- 79 + 31532653 = 31532732
- 139 + 31532593 = 31532732
- 151 + 31532581 = 31532732
- 181 + 31532551 = 31532732
- 193 + 31532539 = 31532732
- 211 + 31532521 = 31532732
- 331 + 31532401 = 31532732
Showing the first eight; more decompositions exist.
