Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040290, here are decompositions:

71 + 1040219 = 1040290
101 + 1040189 = 1040290
107 + 1040183 = 1040290
131 + 1040159 = 1040290
137 + 1040153 = 1040290
149 + 1040141 = 1040290
197 + 1040093 = 1040290
233 + 1040057 = 1040290

Showing the first eight; more decompositions exist.
