Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649962, here are decompositions:

109 + 8649853 = 8649962
199 + 8649763 = 8649962
241 + 8649721 = 8649962
271 + 8649691 = 8649962
499 + 8649463 = 8649962
571 + 8649391 = 8649962
613 + 8649349 = 8649962
619 + 8649343 = 8649962

Showing the first eight; more decompositions exist.
