Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617328, here are decompositions:
- 47 + 31617281 = 31617328
- 59 + 31617269 = 31617328
- 89 + 31617239 = 31617328
- 179 + 31617149 = 31617328
- 227 + 31617101 = 31617328
- 251 + 31617077 = 31617328
- 317 + 31617011 = 31617328
- 599 + 31616729 = 31617328
Showing the first eight; more decompositions exist.
