Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700690, here are decompositions:

41 + 8700649 = 8700690
101 + 8700589 = 8700690
109 + 8700581 = 8700690
127 + 8700563 = 8700690
151 + 8700539 = 8700690
179 + 8700511 = 8700690
223 + 8700467 = 8700690
233 + 8700457 = 8700690

Showing the first eight; more decompositions exist.
