Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450678, here are decompositions:
- 11 + 31450667 = 31450678
- 59 + 31450619 = 31450678
- 89 + 31450589 = 31450678
- 101 + 31450577 = 31450678
- 137 + 31450541 = 31450678
- 191 + 31450487 = 31450678
- 227 + 31450451 = 31450678
- 251 + 31450427 = 31450678
Showing the first eight; more decompositions exist.
