Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018128, here are decompositions:

5 + 1018123 = 1018128
19 + 1018109 = 1018128
31 + 1018097 = 1018128
37 + 1018091 = 1018128
71 + 1018057 = 1018128
107 + 1018021 = 1018128
109 + 1018019 = 1018128
131 + 1017997 = 1018128

Showing the first eight; more decompositions exist.
