Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726618, here are decompositions:

7 + 8726611 = 8726618
31 + 8726587 = 8726618
97 + 8726521 = 8726618
139 + 8726479 = 8726618
151 + 8726467 = 8726618
157 + 8726461 = 8726618
379 + 8726239 = 8726618
409 + 8726209 = 8726618

Showing the first eight; more decompositions exist.
