Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550, here are decompositions:
- 3 + 31547 = 31550
- 7 + 31543 = 31550
- 19 + 31531 = 31550
- 37 + 31513 = 31550
- 61 + 31489 = 31550
- 73 + 31477 = 31550
- 157 + 31393 = 31550
- 163 + 31387 = 31550
Showing the first eight; more decompositions exist.
