Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649876, here are decompositions:

5 + 8649871 = 8649876
7 + 8649869 = 8649876
19 + 8649857 = 8649876
23 + 8649853 = 8649876
29 + 8649847 = 8649876
73 + 8649803 = 8649876
83 + 8649793 = 8649876
113 + 8649763 = 8649876

Showing the first eight; more decompositions exist.
