Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738564, here are decompositions:

31 + 8738533 = 8738564
73 + 8738491 = 8738564
127 + 8738437 = 8738564
157 + 8738407 = 8738564
181 + 8738383 = 8738564
271 + 8738293 = 8738564
283 + 8738281 = 8738564
337 + 8738227 = 8738564

Showing the first eight; more decompositions exist.
