Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691610, here are decompositions:

17 + 8691593 = 8691610
23 + 8691587 = 8691610
29 + 8691581 = 8691610
101 + 8691509 = 8691610
113 + 8691497 = 8691610
131 + 8691479 = 8691610
197 + 8691413 = 8691610
227 + 8691383 = 8691610

Showing the first eight; more decompositions exist.
