Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732560, here are decompositions:

59 + 8732501 = 8732560
71 + 8732489 = 8732560
113 + 8732447 = 8732560
131 + 8732429 = 8732560
149 + 8732411 = 8732560
191 + 8732369 = 8732560
197 + 8732363 = 8732560
251 + 8732309 = 8732560

Showing the first eight; more decompositions exist.
