Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623618, here are decompositions:

71 + 8623547 = 8623618
89 + 8623529 = 8623618
557 + 8623061 = 8623618
587 + 8623031 = 8623618
599 + 8623019 = 8623618
659 + 8622959 = 8623618
761 + 8622857 = 8623618
911 + 8622707 = 8623618

Showing the first eight; more decompositions exist.
