Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011620, here are decompositions:

19 + 1011601 = 1011620
31 + 1011589 = 1011620
37 + 1011583 = 1011620
61 + 1011559 = 1011620
67 + 1011553 = 1011620
223 + 1011397 = 1011620
229 + 1011391 = 1011620
271 + 1011349 = 1011620

Showing the first eight; more decompositions exist.
