Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518954, here are decompositions:

43 + 518911 = 518954
61 + 518893 = 518954
151 + 518803 = 518954
193 + 518761 = 518954
211 + 518743 = 518954
367 + 518587 = 518954
421 + 518533 = 518954
433 + 518521 = 518954

Showing the first eight; more decompositions exist.
