Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463210, here are decompositions:
- 7 + 31463203 = 31463210
- 13 + 31463197 = 31463210
- 43 + 31463167 = 31463210
- 73 + 31463137 = 31463210
- 127 + 31463083 = 31463210
- 241 + 31462969 = 31463210
- 277 + 31462933 = 31463210
- 313 + 31462897 = 31463210
Showing the first eight; more decompositions exist.
