Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726648, here are decompositions:

37 + 8726611 = 8726648
61 + 8726587 = 8726648
79 + 8726569 = 8726648
127 + 8726521 = 8726648
181 + 8726467 = 8726648
199 + 8726449 = 8726648
409 + 8726239 = 8726648
421 + 8726227 = 8726648

Showing the first eight; more decompositions exist.
