Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463208, here are decompositions:
- 5 + 31463203 = 31463208
- 11 + 31463197 = 31463208
- 41 + 31463167 = 31463208
- 47 + 31463161 = 31463208
- 61 + 31463147 = 31463208
- 71 + 31463137 = 31463208
- 109 + 31463099 = 31463208
- 131 + 31463077 = 31463208
Showing the first eight; more decompositions exist.
