Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019664, here are decompositions:

7 + 1019657 = 1019664
17 + 1019647 = 1019664
47 + 1019617 = 1019664
101 + 1019563 = 1019664
127 + 1019537 = 1019664
131 + 1019533 = 1019664
193 + 1019471 = 1019664
197 + 1019467 = 1019664

Showing the first eight; more decompositions exist.
