Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476816, here are decompositions:
- 17 + 31476799 = 31476816
- 73 + 31476743 = 31476816
- 83 + 31476733 = 31476816
- 89 + 31476727 = 31476816
- 113 + 31476703 = 31476816
- 193 + 31476623 = 31476816
- 223 + 31476593 = 31476816
- 229 + 31476587 = 31476816
Showing the first eight; more decompositions exist.
