Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678998, here are decompositions:

47 + 8678951 = 8678998
59 + 8678939 = 8678998
71 + 8678927 = 8678998
239 + 8678759 = 8678998
257 + 8678741 = 8678998
359 + 8678639 = 8678998
479 + 8678519 = 8678998
491 + 8678507 = 8678998

Showing the first eight; more decompositions exist.
