Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620804, here are decompositions:

47 + 8620757 = 8620804
83 + 8620721 = 8620804
113 + 8620691 = 8620804
131 + 8620673 = 8620804
167 + 8620637 = 8620804
173 + 8620631 = 8620804
233 + 8620571 = 8620804
251 + 8620553 = 8620804

Showing the first eight; more decompositions exist.
