Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620906, here are decompositions:

59 + 8620847 = 8620906
149 + 8620757 = 8620906
167 + 8620739 = 8620906
179 + 8620727 = 8620906
233 + 8620673 = 8620906
269 + 8620637 = 8620906
317 + 8620589 = 8620906
353 + 8620553 = 8620906

Showing the first eight; more decompositions exist.
