Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518948, here are decompositions:

37 + 518911 = 518948
139 + 518809 = 518948
181 + 518767 = 518948
211 + 518737 = 518948
337 + 518611 = 518948
439 + 518509 = 518948
607 + 518341 = 518948
709 + 518239 = 518948

Showing the first eight; more decompositions exist.
