Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522960, here are decompositions:
- 23 + 31522937 = 31522960
- 59 + 31522901 = 31522960
- 71 + 31522889 = 31522960
- 113 + 31522847 = 31522960
- 137 + 31522823 = 31522960
- 347 + 31522613 = 31522960
- 419 + 31522541 = 31522960
- 431 + 31522529 = 31522960
Showing the first eight; more decompositions exist.
