Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752520, here are decompositions:

13 + 8752507 = 8752520
43 + 8752477 = 8752520
79 + 8752441 = 8752520
103 + 8752417 = 8752520
181 + 8752339 = 8752520
193 + 8752327 = 8752520
199 + 8752321 = 8752520
211 + 8752309 = 8752520

Showing the first eight; more decompositions exist.
