Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518764, here are decompositions:
- 7 + 31518757 = 31518764
- 73 + 31518691 = 31518764
- 157 + 31518607 = 31518764
- 163 + 31518601 = 31518764
- 223 + 31518541 = 31518764
- 241 + 31518523 = 31518764
- 283 + 31518481 = 31518764
- 307 + 31518457 = 31518764
Showing the first eight; more decompositions exist.
