Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620746, here are decompositions:

7 + 8620739 = 8620746
19 + 8620727 = 8620746
23 + 8620723 = 8620746
59 + 8620687 = 8620746
73 + 8620673 = 8620746
83 + 8620663 = 8620746
107 + 8620639 = 8620746
109 + 8620637 = 8620746

Showing the first eight; more decompositions exist.
