Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516750, here are decompositions:
- 47 + 31516703 = 31516750
- 53 + 31516697 = 31516750
- 131 + 31516619 = 31516750
- 137 + 31516613 = 31516750
- 179 + 31516571 = 31516750
- 191 + 31516559 = 31516750
- 227 + 31516523 = 31516750
- 257 + 31516493 = 31516750
Showing the first eight; more decompositions exist.
