Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522760, here are decompositions:
- 13 + 31522747 = 31522760
- 43 + 31522717 = 31522760
- 67 + 31522693 = 31522760
- 97 + 31522663 = 31522760
- 103 + 31522657 = 31522760
- 127 + 31522633 = 31522760
- 163 + 31522597 = 31522760
- 211 + 31522549 = 31522760
Showing the first eight; more decompositions exist.
