Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566670, here are decompositions:
- 11 + 31566659 = 31566670
- 59 + 31566611 = 31566670
- 71 + 31566599 = 31566670
- 173 + 31566497 = 31566670
- 197 + 31566473 = 31566670
- 227 + 31566443 = 31566670
- 281 + 31566389 = 31566670
- 293 + 31566377 = 31566670
Showing the first eight; more decompositions exist.
