Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532670, here are decompositions:
- 11 + 31532659 = 31532670
- 17 + 31532653 = 31532670
- 31 + 31532639 = 31532670
- 73 + 31532597 = 31532670
- 83 + 31532587 = 31532670
- 89 + 31532581 = 31532670
- 97 + 31532573 = 31532670
- 131 + 31532539 = 31532670
Showing the first eight; more decompositions exist.
