Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028818, here are decompositions:

41 + 1028777 = 1028818
71 + 1028747 = 1028818
137 + 1028681 = 1028818
149 + 1028669 = 1028818
239 + 1028579 = 1028818
257 + 1028561 = 1028818
347 + 1028471 = 1028818
491 + 1028327 = 1028818

Showing the first eight; more decompositions exist.
