Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639514, here are decompositions:

7 + 8639507 = 8639514
53 + 8639461 = 8639514
61 + 8639453 = 8639514
71 + 8639443 = 8639514
73 + 8639441 = 8639514
101 + 8639413 = 8639514
113 + 8639401 = 8639514
151 + 8639363 = 8639514

Showing the first eight; more decompositions exist.
