Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661758, here are decompositions:

31 + 8661727 = 8661758
181 + 8661577 = 8661758
229 + 8661529 = 8661758
271 + 8661487 = 8661758
331 + 8661427 = 8661758
541 + 8661217 = 8661758
577 + 8661181 = 8661758
709 + 8661049 = 8661758

Showing the first eight; more decompositions exist.
