Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039728, here are decompositions:

47 + 1039681 = 1039728
61 + 1039667 = 1039728
71 + 1039657 = 1039728
97 + 1039631 = 1039728
191 + 1039537 = 1039728
211 + 1039517 = 1039728
251 + 1039477 = 1039728
307 + 1039421 = 1039728

Showing the first eight; more decompositions exist.
