Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661938, here are decompositions:

37 + 8661901 = 8661938
67 + 8661871 = 8661938
97 + 8661841 = 8661938
139 + 8661799 = 8661938
211 + 8661727 = 8661938
367 + 8661571 = 8661938
409 + 8661529 = 8661938
499 + 8661439 = 8661938

Showing the first eight; more decompositions exist.
