Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738828, here are decompositions:

19 + 8738809 = 8738828
61 + 8738767 = 8738828
157 + 8738671 = 8738828
337 + 8738491 = 8738828
379 + 8738449 = 8738828
421 + 8738407 = 8738828
547 + 8738281 = 8738828
601 + 8738227 = 8738828

Showing the first eight; more decompositions exist.
