Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023618, here are decompositions:

17 + 1023601 = 1023618
41 + 1023577 = 1023618
47 + 1023571 = 1023618
61 + 1023557 = 1023618
67 + 1023551 = 1023618
97 + 1023521 = 1023618
131 + 1023487 = 1023618
151 + 1023467 = 1023618

Showing the first eight; more decompositions exist.
