Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738426, here are decompositions:

19 + 8738407 = 8738426
43 + 8738383 = 8738426
127 + 8738299 = 8738426
163 + 8738263 = 8738426
199 + 8738227 = 8738426
337 + 8738089 = 8738426
373 + 8738053 = 8738426
379 + 8738047 = 8738426

Showing the first eight; more decompositions exist.
