Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621256, here are decompositions:

13 + 8621243 = 8621256
19 + 8621237 = 8621256
43 + 8621213 = 8621256
47 + 8621209 = 8621256
67 + 8621189 = 8621256
73 + 8621183 = 8621256
103 + 8621153 = 8621256
109 + 8621147 = 8621256

Showing the first eight; more decompositions exist.
