Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985620, here are decompositions:

7 + 985613 = 985620
19 + 985601 = 985620
23 + 985597 = 985620
73 + 985547 = 985620
89 + 985531 = 985620
101 + 985519 = 985620
127 + 985493 = 985620
137 + 985483 = 985620

Showing the first eight; more decompositions exist.
