Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026620, here are decompositions:

37 + 1026583 = 1026620
43 + 1026577 = 1026620
73 + 1026547 = 1026620
139 + 1026481 = 1026620
163 + 1026457 = 1026620
181 + 1026439 = 1026620
193 + 1026427 = 1026620
229 + 1026391 = 1026620

Showing the first eight; more decompositions exist.
