Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023918, here are decompositions:

47 + 1023871 = 1023918
61 + 1023857 = 1023918
67 + 1023851 = 1023918
79 + 1023839 = 1023918
97 + 1023821 = 1023918
149 + 1023769 = 1023918
167 + 1023751 = 1023918
197 + 1023721 = 1023918

Showing the first eight; more decompositions exist.
