Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618026, here are decompositions:

5 + 8618021 = 8618026
83 + 8617943 = 8618026
149 + 8617877 = 8618026
227 + 8617799 = 8618026
239 + 8617787 = 8618026
257 + 8617769 = 8618026
479 + 8617547 = 8618026
503 + 8617523 = 8618026

Showing the first eight; more decompositions exist.
