Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661488, here are decompositions:

19 + 8661469 = 8661488
61 + 8661427 = 8661488
271 + 8661217 = 8661488
307 + 8661181 = 8661488
439 + 8661049 = 8661488
487 + 8661001 = 8661488
541 + 8660947 = 8661488
601 + 8660887 = 8661488

Showing the first eight; more decompositions exist.
