Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739688, here are decompositions:

17 + 8739671 = 8739688
71 + 8739617 = 8739688
197 + 8739491 = 8739688
257 + 8739431 = 8739688
389 + 8739299 = 8739688
479 + 8739209 = 8739688
491 + 8739197 = 8739688
521 + 8739167 = 8739688

Showing the first eight; more decompositions exist.
