Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018732, here are decompositions:

3 + 1018729 = 1018732
23 + 1018709 = 1018732
53 + 1018679 = 1018732
59 + 1018673 = 1018732
83 + 1018649 = 1018732
89 + 1018643 = 1018732
149 + 1018583 = 1018732
173 + 1018559 = 1018732

Showing the first eight; more decompositions exist.
