Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676940, here are decompositions:

3 + 8676937 = 8676940
47 + 8676893 = 8676940
113 + 8676827 = 8676940
197 + 8676743 = 8676940
281 + 8676659 = 8676940
353 + 8676587 = 8676940
491 + 8676449 = 8676940
509 + 8676431 = 8676940

Showing the first eight; more decompositions exist.
