Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516850, here are decompositions:
- 31 + 31516819 = 31516850
- 61 + 31516789 = 31516850
- 73 + 31516777 = 31516850
- 97 + 31516753 = 31516850
- 151 + 31516699 = 31516850
- 181 + 31516669 = 31516850
- 223 + 31516627 = 31516850
- 283 + 31516567 = 31516850
Showing the first eight; more decompositions exist.
