Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712530, here are decompositions:

7 + 8712523 = 8712530
109 + 8712421 = 8712530
157 + 8712373 = 8712530
163 + 8712367 = 8712530
181 + 8712349 = 8712530
193 + 8712337 = 8712530
223 + 8712307 = 8712530
271 + 8712259 = 8712530

Showing the first eight; more decompositions exist.
