Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570560, here are decompositions:
- 41 + 31570519 = 31570560
- 53 + 31570507 = 31570560
- 59 + 31570501 = 31570560
- 61 + 31570499 = 31570560
- 79 + 31570481 = 31570560
- 101 + 31570459 = 31570560
- 113 + 31570447 = 31570560
- 163 + 31570397 = 31570560
Showing the first eight; more decompositions exist.
