Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620166, here are decompositions:

7 + 8620159 = 8620166
97 + 8620069 = 8620166
103 + 8620063 = 8620166
223 + 8619943 = 8620166
229 + 8619937 = 8620166
283 + 8619883 = 8620166
307 + 8619859 = 8620166
349 + 8619817 = 8620166

Showing the first eight; more decompositions exist.
