Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738568, here are decompositions:

29 + 8738539 = 8738568
61 + 8738507 = 8738568
131 + 8738437 = 8738568
191 + 8738377 = 8738568
229 + 8738339 = 8738568
269 + 8738299 = 8738568
337 + 8738231 = 8738568
359 + 8738209 = 8738568

Showing the first eight; more decompositions exist.
