Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019090, here are decompositions:

13 + 1019077 = 1019090
19 + 1019071 = 1019090
31 + 1019059 = 1019090
67 + 1019023 = 1019090
97 + 1018993 = 1019090
103 + 1018987 = 1019090
109 + 1018981 = 1019090
211 + 1018879 = 1019090

Showing the first eight; more decompositions exist.
