Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523250, here are decompositions:
- 7 + 31523243 = 31523250
- 13 + 31523237 = 31523250
- 19 + 31523231 = 31523250
- 23 + 31523227 = 31523250
- 29 + 31523221 = 31523250
- 41 + 31523209 = 31523250
- 43 + 31523207 = 31523250
- 89 + 31523161 = 31523250
Showing the first eight; more decompositions exist.
