Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51506, here are decompositions:

3 + 51503 = 51506
19 + 51487 = 51506
67 + 51439 = 51506
79 + 51427 = 51506
157 + 51349 = 51506
163 + 51343 = 51506
199 + 51307 = 51506
223 + 51283 = 51506

Showing the first eight; more decompositions exist.
