Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621226, here are decompositions:

13 + 8621213 = 8621226
17 + 8621209 = 8621226
37 + 8621189 = 8621226
43 + 8621183 = 8621226
73 + 8621153 = 8621226
79 + 8621147 = 8621226
83 + 8621143 = 8621226
137 + 8621089 = 8621226

Showing the first eight; more decompositions exist.
