Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618020, here are decompositions:

29 + 8617991 = 8618020
71 + 8617949 = 8618020
149 + 8617871 = 8618020
197 + 8617823 = 8618020
233 + 8617787 = 8618020
251 + 8617769 = 8618020
317 + 8617703 = 8618020
647 + 8617373 = 8618020

Showing the first eight; more decompositions exist.
