Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 50990, here are decompositions:

19 + 50971 = 50990
61 + 50929 = 50990
67 + 50923 = 50990
97 + 50893 = 50990
151 + 50839 = 50990
157 + 50833 = 50990
223 + 50767 = 50990
283 + 50707 = 50990

Showing the first eight; more decompositions exist.
