Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639612, here are decompositions:

13 + 8639599 = 8639612
61 + 8639551 = 8639612
73 + 8639539 = 8639612
151 + 8639461 = 8639612
199 + 8639413 = 8639612
211 + 8639401 = 8639612
313 + 8639299 = 8639612
349 + 8639263 = 8639612

Showing the first eight; more decompositions exist.
