Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522710, here are decompositions:
- 17 + 31522693 = 31522710
- 41 + 31522669 = 31522710
- 47 + 31522663 = 31522710
- 53 + 31522657 = 31522710
- 97 + 31522613 = 31522710
- 113 + 31522597 = 31522710
- 127 + 31522583 = 31522710
- 157 + 31522553 = 31522710
Showing the first eight; more decompositions exist.
