Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042178, here are decompositions:

37 + 1042141 = 1042178
79 + 1042099 = 1042178
97 + 1042081 = 1042178
139 + 1042039 = 1042178
157 + 1042021 = 1042178
229 + 1041949 = 1042178
271 + 1041907 = 1042178
337 + 1041841 = 1042178

Showing the first eight; more decompositions exist.
