Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017620, here are decompositions:

3 + 1017617 = 1017620
7 + 1017613 = 1017620
13 + 1017607 = 1017620
61 + 1017559 = 1017620
67 + 1017553 = 1017620
139 + 1017481 = 1017620
181 + 1017439 = 1017620
229 + 1017391 = 1017620

Showing the first eight; more decompositions exist.
