Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689630, here are decompositions:

3 + 8689627 = 8689630
101 + 8689529 = 8689630
137 + 8689493 = 8689630
149 + 8689481 = 8689630
167 + 8689463 = 8689630
179 + 8689451 = 8689630
197 + 8689433 = 8689630
281 + 8689349 = 8689630

Showing the first eight; more decompositions exist.
