Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028724, here are decompositions:

41 + 1028683 = 1028724
43 + 1028681 = 1028724
61 + 1028663 = 1028724
107 + 1028617 = 1028724
127 + 1028597 = 1028724
163 + 1028561 = 1028724
167 + 1028557 = 1028724
251 + 1028473 = 1028724

Showing the first eight; more decompositions exist.
