Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621126, here are decompositions:

37 + 8621089 = 8621126
43 + 8621083 = 8621126
79 + 8621047 = 8621126
109 + 8621017 = 8621126
229 + 8620897 = 8621126
379 + 8620747 = 8621126
439 + 8620687 = 8621126
463 + 8620663 = 8621126

Showing the first eight; more decompositions exist.
