Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738672, here are decompositions:

13 + 8738659 = 8738672
31 + 8738641 = 8738672
139 + 8738533 = 8738672
181 + 8738491 = 8738672
199 + 8738473 = 8738672
223 + 8738449 = 8738672
373 + 8738299 = 8738672
379 + 8738293 = 8738672

Showing the first eight; more decompositions exist.
