Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486792, here are decompositions:
- 23 + 31486769 = 31486792
- 41 + 31486751 = 31486792
- 53 + 31486739 = 31486792
- 59 + 31486733 = 31486792
- 83 + 31486709 = 31486792
- 131 + 31486661 = 31486792
- 149 + 31486643 = 31486792
- 179 + 31486613 = 31486792
Showing the first eight; more decompositions exist.
