Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750540, here are decompositions:

13 + 8750527 = 8750540
31 + 8750509 = 8750540
61 + 8750479 = 8750540
163 + 8750377 = 8750540
193 + 8750347 = 8750540
199 + 8750341 = 8750540
307 + 8750233 = 8750540
313 + 8750227 = 8750540

Showing the first eight; more decompositions exist.
