Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039778, here are decompositions:

97 + 1039681 = 1039778
127 + 1039651 = 1039778
241 + 1039537 = 1039778
349 + 1039429 = 1039778
457 + 1039321 = 1039778
499 + 1039279 = 1039778
709 + 1039069 = 1039778
739 + 1039039 = 1039778

Showing the first eight; more decompositions exist.
