Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038778, here are decompositions:

47 + 1038731 = 1038778
71 + 1038707 = 1038778
89 + 1038689 = 1038778
107 + 1038671 = 1038778
149 + 1038629 = 1038778
179 + 1038599 = 1038778
239 + 1038539 = 1038778
281 + 1038497 = 1038778

Showing the first eight; more decompositions exist.
