Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654642, here are decompositions:

79 + 8654563 = 8654642
181 + 8654461 = 8654642
211 + 8654431 = 8654642
421 + 8654221 = 8654642
613 + 8654029 = 8654642
631 + 8654011 = 8654642
739 + 8653903 = 8654642
751 + 8653891 = 8654642

Showing the first eight; more decompositions exist.
