Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752398, here are decompositions:

19 + 8752379 = 8752398
37 + 8752361 = 8752398
59 + 8752339 = 8752398
71 + 8752327 = 8752398
89 + 8752309 = 8752398
107 + 8752291 = 8752398
167 + 8752231 = 8752398
191 + 8752207 = 8752398

Showing the first eight; more decompositions exist.
