Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739938, here are decompositions:

19 + 8739919 = 8739938
37 + 8739901 = 8739938
61 + 8739877 = 8739938
127 + 8739811 = 8739938
199 + 8739739 = 8739938
271 + 8739667 = 8739938
331 + 8739607 = 8739938
409 + 8739529 = 8739938

Showing the first eight; more decompositions exist.
