Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649770, here are decompositions:

7 + 8649763 = 8649770
13 + 8649757 = 8649770
67 + 8649703 = 8649770
79 + 8649691 = 8649770
109 + 8649661 = 8649770
307 + 8649463 = 8649770
379 + 8649391 = 8649770
421 + 8649349 = 8649770

Showing the first eight; more decompositions exist.
