Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752538, here are decompositions:

7 + 8752531 = 8752538
31 + 8752507 = 8752538
61 + 8752477 = 8752538
97 + 8752441 = 8752538
199 + 8752339 = 8752538
211 + 8752327 = 8752538
229 + 8752309 = 8752538
307 + 8752231 = 8752538

Showing the first eight; more decompositions exist.
