Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51814, here are decompositions:

11 + 51803 = 51814
17 + 51797 = 51814
47 + 51767 = 51814
101 + 51713 = 51814
131 + 51683 = 51814
167 + 51647 = 51814
233 + 51581 = 51814
251 + 51563 = 51814

Showing the first eight; more decompositions exist.
