Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661368, here are decompositions:

127 + 8661241 = 8661368
151 + 8661217 = 8661368
307 + 8661061 = 8661368
367 + 8661001 = 8661368
421 + 8660947 = 8661368
439 + 8660929 = 8661368
571 + 8660797 = 8661368
601 + 8660767 = 8661368

Showing the first eight; more decompositions exist.
