Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639078, here are decompositions:

67 + 8639011 = 8639078
79 + 8638999 = 8639078
127 + 8638951 = 8639078
211 + 8638867 = 8639078
229 + 8638849 = 8639078
271 + 8638807 = 8639078
457 + 8638621 = 8639078
601 + 8638477 = 8639078

Showing the first eight; more decompositions exist.
