Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028090, here are decompositions:

43 + 1028047 = 1028090
61 + 1028029 = 1028090
67 + 1028023 = 1028090
73 + 1028017 = 1028090
79 + 1028011 = 1028090
103 + 1027987 = 1028090
199 + 1027891 = 1028090
307 + 1027783 = 1028090

Showing the first eight; more decompositions exist.
