Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621082, here are decompositions:

5 + 8621077 = 8621082
31 + 8621051 = 8621082
73 + 8621009 = 8621082
89 + 8620993 = 8621082
109 + 8620973 = 8621082
131 + 8620951 = 8621082
139 + 8620943 = 8621082
241 + 8620841 = 8621082

Showing the first eight; more decompositions exist.
