Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617300, here are decompositions:
- 7 + 31617293 = 31617300
- 17 + 31617283 = 31617300
- 19 + 31617281 = 31617300
- 31 + 31617269 = 31617300
- 47 + 31617253 = 31617300
- 61 + 31617239 = 31617300
- 101 + 31617199 = 31617300
- 151 + 31617149 = 31617300
Showing the first eight; more decompositions exist.
