Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639012, here are decompositions:

13 + 8638999 = 8639012
61 + 8638951 = 8639012
79 + 8638933 = 8639012
103 + 8638909 = 8639012
163 + 8638849 = 8639012
379 + 8638633 = 8639012
541 + 8638471 = 8639012
601 + 8638411 = 8639012

Showing the first eight; more decompositions exist.
