Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649930, here are decompositions:

19 + 8649911 = 8649930
43 + 8649887 = 8649930
59 + 8649871 = 8649930
61 + 8649869 = 8649930
73 + 8649857 = 8649930
83 + 8649847 = 8649930
127 + 8649803 = 8649930
137 + 8649793 = 8649930

Showing the first eight; more decompositions exist.
