Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019778, here are decompositions:

7 + 1019771 = 1019778
31 + 1019747 = 1019778
37 + 1019741 = 1019778
47 + 1019731 = 1019778
61 + 1019717 = 1019778
79 + 1019699 = 1019778
131 + 1019647 = 1019778
139 + 1019639 = 1019778

Showing the first eight; more decompositions exist.
