Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676580, here are decompositions:

47 + 8676533 = 8676580
53 + 8676527 = 8676580
113 + 8676467 = 8676580
131 + 8676449 = 8676580
149 + 8676431 = 8676580
179 + 8676401 = 8676580
197 + 8676383 = 8676580
293 + 8676287 = 8676580

Showing the first eight; more decompositions exist.
