Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494456, here are decompositions:
- 13 + 31494443 = 31494456
- 17 + 31494439 = 31494456
- 29 + 31494427 = 31494456
- 67 + 31494389 = 31494456
- 109 + 31494347 = 31494456
- 163 + 31494293 = 31494456
- 193 + 31494263 = 31494456
- 199 + 31494257 = 31494456
Showing the first eight; more decompositions exist.
