Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518942, here are decompositions:

31 + 518911 = 518942
79 + 518863 = 518942
139 + 518803 = 518942
163 + 518779 = 518942
181 + 518761 = 518942
199 + 518743 = 518942
331 + 518611 = 518942
409 + 518533 = 518942

Showing the first eight; more decompositions exist.
