Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608, here are decompositions:
- 7 + 31601 = 31608
- 41 + 31567 = 31608
- 61 + 31547 = 31608
- 67 + 31541 = 31608
- 97 + 31511 = 31608
- 127 + 31481 = 31608
- 131 + 31477 = 31608
- 139 + 31469 = 31608
Showing the first eight; more decompositions exist.
