Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026590, here are decompositions:

3 + 1026587 = 1026590
7 + 1026583 = 1026590
13 + 1026577 = 1026590
43 + 1026547 = 1026590
109 + 1026481 = 1026590
151 + 1026439 = 1026590
163 + 1026427 = 1026590
199 + 1026391 = 1026590

Showing the first eight; more decompositions exist.
