Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51662, here are decompositions:

3 + 51659 = 51662
31 + 51631 = 51662
151 + 51511 = 51662
181 + 51481 = 51662
223 + 51439 = 51662
241 + 51421 = 51662
313 + 51349 = 51662
379 + 51283 = 51662

Showing the first eight; more decompositions exist.
