Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746580, here are decompositions:

61 + 8746519 = 8746580
67 + 8746513 = 8746580
127 + 8746453 = 8746580
181 + 8746399 = 8746580
211 + 8746369 = 8746580
223 + 8746357 = 8746580
229 + 8746351 = 8746580
277 + 8746303 = 8746580

Showing the first eight; more decompositions exist.
