Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678590, here are decompositions:

3 + 8678587 = 8678590
71 + 8678519 = 8678590
83 + 8678507 = 8678590
191 + 8678399 = 8678590
197 + 8678393 = 8678590
227 + 8678363 = 8678590
251 + 8678339 = 8678590
257 + 8678333 = 8678590

Showing the first eight; more decompositions exist.
