Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584, here are decompositions:
- 11 + 31573 = 31584
- 17 + 31567 = 31584
- 37 + 31547 = 31584
- 41 + 31543 = 31584
- 43 + 31541 = 31584
- 53 + 31531 = 31584
- 67 + 31517 = 31584
- 71 + 31513 = 31584
Showing the first eight; more decompositions exist.
