Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543344, here are decompositions:
- 13 + 31543331 = 31543344
- 43 + 31543301 = 31543344
- 71 + 31543273 = 31543344
- 101 + 31543243 = 31543344
- 113 + 31543231 = 31543344
- 127 + 31543217 = 31543344
- 137 + 31543207 = 31543344
- 163 + 31543181 = 31543344
Showing the first eight; more decompositions exist.
