Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023290, here are decompositions:

13 + 1023277 = 1023290
31 + 1023259 = 1023290
61 + 1023229 = 1023290
127 + 1023163 = 1023290
157 + 1023133 = 1023290
211 + 1023079 = 1023290
223 + 1023067 = 1023290
271 + 1023019 = 1023290

Showing the first eight; more decompositions exist.
