Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49990, here are decompositions:

47 + 49943 = 49990
53 + 49937 = 49990
71 + 49919 = 49990
113 + 49877 = 49990
137 + 49853 = 49990
167 + 49823 = 49990
179 + 49811 = 49990
233 + 49757 = 49990

Showing the first eight; more decompositions exist.
