Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621196, here are decompositions:

7 + 8621189 = 8621196
13 + 8621183 = 8621196
43 + 8621153 = 8621196
53 + 8621143 = 8621196
107 + 8621089 = 8621196
109 + 8621087 = 8621196
113 + 8621083 = 8621196
149 + 8621047 = 8621196

Showing the first eight; more decompositions exist.
