Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522624, here are decompositions:
- 11 + 31522613 = 31522624
- 41 + 31522583 = 31522624
- 71 + 31522553 = 31522624
- 83 + 31522541 = 31522624
- 101 + 31522523 = 31522624
- 131 + 31522493 = 31522624
- 173 + 31522451 = 31522624
- 191 + 31522433 = 31522624
Showing the first eight; more decompositions exist.
