Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649860, here are decompositions:

3 + 8649857 = 8649860
7 + 8649853 = 8649860
13 + 8649847 = 8649860
67 + 8649793 = 8649860
97 + 8649763 = 8649860
103 + 8649757 = 8649860
139 + 8649721 = 8649860
157 + 8649703 = 8649860

Showing the first eight; more decompositions exist.
