Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661562, here are decompositions:

5 + 8661557 = 8661562
53 + 8661509 = 8661562
71 + 8661491 = 8661562
83 + 8661479 = 8661562
101 + 8661461 = 8661562
149 + 8661413 = 8661562
179 + 8661383 = 8661562
251 + 8661311 = 8661562

Showing the first eight; more decompositions exist.
