Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019950, here are decompositions:

23 + 1019927 = 1019950
47 + 1019903 = 1019950
89 + 1019861 = 1019950
101 + 1019849 = 1019950
131 + 1019819 = 1019950
149 + 1019801 = 1019950
167 + 1019783 = 1019950
179 + 1019771 = 1019950

Showing the first eight; more decompositions exist.
