Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683942, here are decompositions:

89 + 8683853 = 8683942
149 + 8683793 = 8683942
173 + 8683769 = 8683942
251 + 8683691 = 8683942
389 + 8683553 = 8683942
401 + 8683541 = 8683942
419 + 8683523 = 8683942
431 + 8683511 = 8683942

Showing the first eight; more decompositions exist.
