Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042090, here are decompositions:

3 + 1042087 = 1042090
47 + 1042043 = 1042090
89 + 1042001 = 1042090
107 + 1041983 = 1042090
197 + 1041893 = 1042090
227 + 1041863 = 1042090
233 + 1041857 = 1042090
311 + 1041779 = 1042090

Showing the first eight; more decompositions exist.
