Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042618, here are decompositions:

11 + 1042607 = 1042618
41 + 1042577 = 1042618
47 + 1042571 = 1042618
89 + 1042529 = 1042618
131 + 1042487 = 1042618
149 + 1042469 = 1042618
167 + 1042451 = 1042618
179 + 1042439 = 1042618

Showing the first eight; more decompositions exist.
