Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684670, here are decompositions:

13 + 8684657 = 8684670
41 + 8684629 = 8684670
73 + 8684597 = 8684670
83 + 8684587 = 8684670
97 + 8684573 = 8684670
149 + 8684521 = 8684670
157 + 8684513 = 8684670
167 + 8684503 = 8684670

Showing the first eight; more decompositions exist.
