Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601938, here are decompositions:

31 + 8601907 = 8601938
61 + 8601877 = 8601938
199 + 8601739 = 8601938
211 + 8601727 = 8601938
271 + 8601667 = 8601938
307 + 8601631 = 8601938
439 + 8601499 = 8601938
547 + 8601391 = 8601938

Showing the first eight; more decompositions exist.
