Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654628, here are decompositions:

7 + 8654621 = 8654628
11 + 8654617 = 8654628
19 + 8654609 = 8654628
107 + 8654521 = 8654628
139 + 8654489 = 8654628
167 + 8654461 = 8654628
181 + 8654447 = 8654628
197 + 8654431 = 8654628

Showing the first eight; more decompositions exist.
