Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639662, here are decompositions:

23 + 8639639 = 8639662
71 + 8639591 = 8639662
113 + 8639549 = 8639662
131 + 8639531 = 8639662
281 + 8639381 = 8639662
389 + 8639273 = 8639662
401 + 8639261 = 8639662
443 + 8639219 = 8639662

Showing the first eight; more decompositions exist.
