Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712560, here are decompositions:

13 + 8712547 = 8712560
37 + 8712523 = 8712560
139 + 8712421 = 8712560
163 + 8712397 = 8712560
193 + 8712367 = 8712560
211 + 8712349 = 8712560
223 + 8712337 = 8712560
331 + 8712229 = 8712560

Showing the first eight; more decompositions exist.
