Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621268, here are decompositions:

31 + 8621237 = 8621268
59 + 8621209 = 8621268
67 + 8621201 = 8621268
79 + 8621189 = 8621268
167 + 8621101 = 8621268
179 + 8621089 = 8621268
181 + 8621087 = 8621268
191 + 8621077 = 8621268

Showing the first eight; more decompositions exist.
