Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649976, here are decompositions:

3 + 8649973 = 8649976
47 + 8649929 = 8649976
89 + 8649887 = 8649976
107 + 8649869 = 8649976
173 + 8649803 = 8649976
347 + 8649629 = 8649976
353 + 8649623 = 8649976
443 + 8649533 = 8649976

Showing the first eight; more decompositions exist.
