Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516270, here are decompositions:
- 17 + 31516253 = 31516270
- 29 + 31516241 = 31516270
- 113 + 31516157 = 31516270
- 131 + 31516139 = 31516270
- 167 + 31516103 = 31516270
- 263 + 31516007 = 31516270
- 281 + 31515989 = 31516270
- 389 + 31515881 = 31516270
Showing the first eight; more decompositions exist.
