Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497774, here are decompositions:
- 17 + 31497757 = 31497774
- 23 + 31497751 = 31497774
- 37 + 31497737 = 31497774
- 47 + 31497727 = 31497774
- 53 + 31497721 = 31497774
- 67 + 31497707 = 31497774
- 73 + 31497701 = 31497774
- 101 + 31497673 = 31497774
Showing the first eight; more decompositions exist.
