Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738630, here are decompositions:

97 + 8738533 = 8738630
139 + 8738491 = 8738630
157 + 8738473 = 8738630
181 + 8738449 = 8738630
193 + 8738437 = 8738630
223 + 8738407 = 8738630
331 + 8738299 = 8738630
337 + 8738293 = 8738630

Showing the first eight; more decompositions exist.
