Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691670, here are decompositions:

3 + 8691667 = 8691670
17 + 8691653 = 8691670
47 + 8691623 = 8691670
83 + 8691587 = 8691670
89 + 8691581 = 8691670
173 + 8691497 = 8691670
191 + 8691479 = 8691670
257 + 8691413 = 8691670

Showing the first eight; more decompositions exist.
