Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665982, here are decompositions:

43 + 8665939 = 8665982
109 + 8665873 = 8665982
331 + 8665651 = 8665982
349 + 8665633 = 8665982
379 + 8665603 = 8665982
421 + 8665561 = 8665982
439 + 8665543 = 8665982
541 + 8665441 = 8665982

Showing the first eight; more decompositions exist.
