Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649956, here are decompositions:

19 + 8649937 = 8649956
103 + 8649853 = 8649956
109 + 8649847 = 8649956
163 + 8649793 = 8649956
193 + 8649763 = 8649956
199 + 8649757 = 8649956
439 + 8649517 = 8649956
487 + 8649469 = 8649956

Showing the first eight; more decompositions exist.
