Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732680, here are decompositions:

3 + 8732677 = 8732680
41 + 8732639 = 8732680
53 + 8732627 = 8732680
107 + 8732573 = 8732680
179 + 8732501 = 8732680
191 + 8732489 = 8732680
233 + 8732447 = 8732680
251 + 8732429 = 8732680

Showing the first eight; more decompositions exist.
