Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513944, here are decompositions:

7 + 513937 = 513944
73 + 513871 = 513944
103 + 513841 = 513944
163 + 513781 = 513944
271 + 513673 = 513944
313 + 513631 = 513944
433 + 513511 = 513944
463 + 513481 = 513944

Showing the first eight; more decompositions exist.
