Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51854, here are decompositions:

37 + 51817 = 51854
67 + 51787 = 51854
163 + 51691 = 51854
181 + 51673 = 51854
223 + 51631 = 51854
241 + 51613 = 51854
277 + 51577 = 51854
337 + 51517 = 51854

Showing the first eight; more decompositions exist.
