Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039878, here are decompositions:

41 + 1039837 = 1039878
61 + 1039817 = 1039878
79 + 1039799 = 1039878
89 + 1039789 = 1039878
109 + 1039769 = 1039878
197 + 1039681 = 1039878
211 + 1039667 = 1039878
227 + 1039651 = 1039878

Showing the first eight; more decompositions exist.
