Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51128, here are decompositions:

19 + 51109 = 51128
67 + 51061 = 51128
97 + 51031 = 51128
127 + 51001 = 51128
139 + 50989 = 51128
157 + 50971 = 51128
199 + 50929 = 51128
271 + 50857 = 51128

Showing the first eight; more decompositions exist.
