Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732580, here are decompositions:

7 + 8732573 = 8732580
29 + 8732551 = 8732580
79 + 8732501 = 8732580
107 + 8732473 = 8732580
149 + 8732431 = 8732580
151 + 8732429 = 8732580
163 + 8732417 = 8732580
211 + 8732369 = 8732580

Showing the first eight; more decompositions exist.
