Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018692, here are decompositions:

13 + 1018679 = 1018692
19 + 1018673 = 1018692
23 + 1018669 = 1018692
41 + 1018651 = 1018692
43 + 1018649 = 1018692
71 + 1018621 = 1018692
79 + 1018613 = 1018692
109 + 1018583 = 1018692

Showing the first eight; more decompositions exist.
