Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518864, here are decompositions:

61 + 518803 = 518864
97 + 518767 = 518864
103 + 518761 = 518864
127 + 518737 = 518864
277 + 518587 = 518864
331 + 518533 = 518864
397 + 518467 = 518864
433 + 518431 = 518864

Showing the first eight; more decompositions exist.
