Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712520, here are decompositions:

23 + 8712497 = 8712520
29 + 8712491 = 8712520
149 + 8712371 = 8712520
197 + 8712323 = 8712520
227 + 8712293 = 8712520
233 + 8712287 = 8712520
239 + 8712281 = 8712520
251 + 8712269 = 8712520

Showing the first eight; more decompositions exist.
