Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51712, here are decompositions:
- 29 + 51683 = 51712
- 53 + 51659 = 51712
- 113 + 51599 = 51712
- 131 + 51581 = 51712
- 149 + 51563 = 51712
- 173 + 51539 = 51712
- 191 + 51521 = 51712
- 233 + 51479 = 51712
Showing the first eight; more decompositions exist.
