Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620822, here are decompositions:

83 + 8620739 = 8620822
101 + 8620721 = 8620822
131 + 8620691 = 8620822
149 + 8620673 = 8620822
191 + 8620631 = 8620822
233 + 8620589 = 8620822
251 + 8620571 = 8620822
269 + 8620553 = 8620822

Showing the first eight; more decompositions exist.
