Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028188, here are decompositions:

47 + 1028141 = 1028188
59 + 1028129 = 1028188
71 + 1028117 = 1028188
89 + 1028099 = 1028188
107 + 1028081 = 1028188
137 + 1028051 = 1028188
257 + 1027931 = 1028188
347 + 1027841 = 1028188

Showing the first eight; more decompositions exist.
