Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018854, here are decompositions:

37 + 1018817 = 1018854
41 + 1018813 = 1018854
43 + 1018811 = 1018854
47 + 1018807 = 1018854
157 + 1018697 = 1018854
181 + 1018673 = 1018854
211 + 1018643 = 1018854
233 + 1018621 = 1018854

Showing the first eight; more decompositions exist.
