Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716580, here are decompositions:

13 + 8716567 = 8716580
127 + 8716453 = 8716580
139 + 8716441 = 8716580
151 + 8716429 = 8716580
199 + 8716381 = 8716580
331 + 8716249 = 8716580
337 + 8716243 = 8716580
373 + 8716207 = 8716580

Showing the first eight; more decompositions exist.
