Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018812, here are decompositions:

5 + 1018807 = 1018812
23 + 1018789 = 1018812
43 + 1018769 = 1018812
79 + 1018733 = 1018812
83 + 1018729 = 1018812
101 + 1018711 = 1018812
103 + 1018709 = 1018812
139 + 1018673 = 1018812

Showing the first eight; more decompositions exist.
