Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738590, here are decompositions:

11 + 8738579 = 8738590
23 + 8738567 = 8738590
83 + 8738507 = 8738590
191 + 8738399 = 8738590
227 + 8738363 = 8738590
239 + 8738351 = 8738590
251 + 8738339 = 8738590
257 + 8738333 = 8738590

Showing the first eight; more decompositions exist.
