Goldbach decomposition

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.
