Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028624, here are decompositions:

7 + 1028617 = 1028624
43 + 1028581 = 1028624
67 + 1028557 = 1028624
151 + 1028473 = 1028624
307 + 1028317 = 1028624
433 + 1028191 = 1028624
523 + 1028101 = 1028624
577 + 1028047 = 1028624

Showing the first eight; more decompositions exist.
