Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532790, here are decompositions:
- 13 + 31532777 = 31532790
- 41 + 31532749 = 31532790
- 53 + 31532737 = 31532790
- 97 + 31532693 = 31532790
- 103 + 31532687 = 31532790
- 131 + 31532659 = 31532790
- 137 + 31532653 = 31532790
- 151 + 31532639 = 31532790
Showing the first eight; more decompositions exist.
