Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51718, here are decompositions:

5 + 51713 = 51718
59 + 51659 = 51718
71 + 51647 = 51718
137 + 51581 = 51718
167 + 51551 = 51718
179 + 51539 = 51718
197 + 51521 = 51718
239 + 51479 = 51718

Showing the first eight; more decompositions exist.
