Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516930, here are decompositions:
- 41 + 31516889 = 31516930
- 89 + 31516841 = 31516930
- 149 + 31516781 = 31516930
- 173 + 31516757 = 31516930
- 227 + 31516703 = 31516930
- 233 + 31516697 = 31516930
- 311 + 31516619 = 31516930
- 317 + 31516613 = 31516930
Showing the first eight; more decompositions exist.
