Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621132, here are decompositions:

31 + 8621101 = 8621132
43 + 8621089 = 8621132
139 + 8620993 = 8621132
181 + 8620951 = 8621132
271 + 8620861 = 8621132
409 + 8620723 = 8621132
739 + 8620393 = 8621132
991 + 8620141 = 8621132

Showing the first eight; more decompositions exist.
