Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018810, here are decompositions:

3 + 1018807 = 1018810
41 + 1018769 = 1018810
47 + 1018763 = 1018810
101 + 1018709 = 1018810
113 + 1018697 = 1018810
131 + 1018679 = 1018810
137 + 1018673 = 1018810
167 + 1018643 = 1018810

Showing the first eight; more decompositions exist.
