Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026290, here are decompositions:

37 + 1026253 = 1026290
61 + 1026229 = 1026290
73 + 1026217 = 1026290
151 + 1026139 = 1026290
163 + 1026127 = 1026290
229 + 1026061 = 1026290
373 + 1025917 = 1026290
379 + 1025911 = 1026290

Showing the first eight; more decompositions exist.
