Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621102, here are decompositions:

13 + 8621089 = 8621102
19 + 8621083 = 8621102
109 + 8620993 = 8621102
151 + 8620951 = 8621102
229 + 8620873 = 8621102
241 + 8620861 = 8621102
379 + 8620723 = 8621102
439 + 8620663 = 8621102

Showing the first eight; more decompositions exist.
