Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620226, here are decompositions:

7 + 8620219 = 8620226
37 + 8620189 = 8620226
67 + 8620159 = 8620226
157 + 8620069 = 8620226
163 + 8620063 = 8620226
229 + 8619997 = 8620226
283 + 8619943 = 8620226
367 + 8619859 = 8620226

Showing the first eight; more decompositions exist.
