Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038978, here are decompositions:

37 + 1038941 = 1038978
41 + 1038937 = 1038978
97 + 1038881 = 1038978
151 + 1038827 = 1038978
167 + 1038811 = 1038978
181 + 1038797 = 1038978
251 + 1038727 = 1038978
257 + 1038721 = 1038978

Showing the first eight; more decompositions exist.
