Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497804, here are decompositions:
- 7 + 31497797 = 31497804
- 31 + 31497773 = 31497804
- 47 + 31497757 = 31497804
- 53 + 31497751 = 31497804
- 67 + 31497737 = 31497804
- 83 + 31497721 = 31497804
- 97 + 31497707 = 31497804
- 103 + 31497701 = 31497804
Showing the first eight; more decompositions exist.
