Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018628, here are decompositions:

7 + 1018621 = 1018628
139 + 1018489 = 1018628
151 + 1018477 = 1018628
157 + 1018471 = 1018628
181 + 1018447 = 1018628
199 + 1018429 = 1018628
271 + 1018357 = 1018628
337 + 1018291 = 1018628

Showing the first eight; more decompositions exist.
