Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018770, here are decompositions:

7 + 1018763 = 1018770
37 + 1018733 = 1018770
41 + 1018729 = 1018770
59 + 1018711 = 1018770
61 + 1018709 = 1018770
73 + 1018697 = 1018770
97 + 1018673 = 1018770
101 + 1018669 = 1018770

Showing the first eight; more decompositions exist.
