Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649694, here are decompositions:

3 + 8649691 = 8649694
5 + 8649689 = 8649694
17 + 8649677 = 8649694
23 + 8649671 = 8649694
71 + 8649623 = 8649694
83 + 8649611 = 8649694
113 + 8649581 = 8649694
173 + 8649521 = 8649694

Showing the first eight; more decompositions exist.
