Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617370, here are decompositions:
- 41 + 31617329 = 31617370
- 89 + 31617281 = 31617370
- 101 + 31617269 = 31617370
- 131 + 31617239 = 31617370
- 269 + 31617101 = 31617370
- 293 + 31617077 = 31617370
- 347 + 31617023 = 31617370
- 359 + 31617011 = 31617370
Showing the first eight; more decompositions exist.
