Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617690, here are decompositions:

167 + 8617523 = 8617690
251 + 8617439 = 8617690
293 + 8617397 = 8617690
317 + 8617373 = 8617690
479 + 8617211 = 8617690
503 + 8617187 = 8617690
593 + 8617097 = 8617690
617 + 8617073 = 8617690

Showing the first eight; more decompositions exist.
