Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664618, here are decompositions:

5 + 8664613 = 8664618
37 + 8664581 = 8664618
59 + 8664559 = 8664618
71 + 8664547 = 8664618
89 + 8664529 = 8664618
101 + 8664517 = 8664618
167 + 8664451 = 8664618
191 + 8664427 = 8664618

Showing the first eight; more decompositions exist.
