Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559722, here are decompositions:
- 3 + 31559719 = 31559722
- 23 + 31559699 = 31559722
- 41 + 31559681 = 31559722
- 71 + 31559651 = 31559722
- 83 + 31559639 = 31559722
- 149 + 31559573 = 31559722
- 251 + 31559471 = 31559722
- 401 + 31559321 = 31559722
Showing the first eight; more decompositions exist.
