Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712528, here are decompositions:

5 + 8712523 = 8712528
31 + 8712497 = 8712528
37 + 8712491 = 8712528
107 + 8712421 = 8712528
131 + 8712397 = 8712528
157 + 8712371 = 8712528
179 + 8712349 = 8712528
191 + 8712337 = 8712528

Showing the first eight; more decompositions exist.
