Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661510, here are decompositions:

19 + 8661491 = 8661510
23 + 8661487 = 8661510
31 + 8661479 = 8661510
41 + 8661469 = 8661510
71 + 8661439 = 8661510
73 + 8661437 = 8661510
83 + 8661427 = 8661510
97 + 8661413 = 8661510

Showing the first eight; more decompositions exist.
