Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038878, here are decompositions:

67 + 1038811 = 1038878
151 + 1038727 = 1038878
157 + 1038721 = 1038878
241 + 1038637 = 1038878
277 + 1038601 = 1038878
349 + 1038529 = 1038878
457 + 1038421 = 1038878
487 + 1038391 = 1038878

Showing the first eight; more decompositions exist.
