Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51750, here are decompositions:

29 + 51721 = 51750
31 + 51719 = 51750
37 + 51713 = 51750
59 + 51691 = 51750
67 + 51683 = 51750
71 + 51679 = 51750
103 + 51647 = 51750
113 + 51637 = 51750

Showing the first eight; more decompositions exist.
