Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661610, here are decompositions:

29 + 8661581 = 8661610
53 + 8661557 = 8661610
101 + 8661509 = 8661610
131 + 8661479 = 8661610
149 + 8661461 = 8661610
173 + 8661437 = 8661610
197 + 8661413 = 8661610
227 + 8661383 = 8661610

Showing the first eight; more decompositions exist.
