Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655670, here are decompositions:

17 + 8655653 = 8655670
29 + 8655641 = 8655670
41 + 8655629 = 8655670
47 + 8655623 = 8655670
59 + 8655611 = 8655670
173 + 8655497 = 8655670
269 + 8655401 = 8655670
383 + 8655287 = 8655670

Showing the first eight; more decompositions exist.
