Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518746, here are decompositions:
- 73 + 31518673 = 31518746
- 139 + 31518607 = 31518746
- 157 + 31518589 = 31518746
- 223 + 31518523 = 31518746
- 367 + 31518379 = 31518746
- 433 + 31518313 = 31518746
- 487 + 31518259 = 31518746
- 607 + 31518139 = 31518746
Showing the first eight; more decompositions exist.
