Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639580, here are decompositions:

13 + 8639567 = 8639580
17 + 8639563 = 8639580
29 + 8639551 = 8639580
31 + 8639549 = 8639580
41 + 8639539 = 8639580
73 + 8639507 = 8639580
127 + 8639453 = 8639580
137 + 8639443 = 8639580

Showing the first eight; more decompositions exist.
