Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019156, here are decompositions:

37 + 1019119 = 1019156
79 + 1019077 = 1019156
97 + 1019059 = 1019156
157 + 1018999 = 1019156
163 + 1018993 = 1019156
199 + 1018957 = 1019156
277 + 1018879 = 1019156
283 + 1018873 = 1019156

Showing the first eight; more decompositions exist.
