Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513752, here are decompositions:

3 + 513749 = 513752
13 + 513739 = 513752
61 + 513691 = 513752
73 + 513679 = 513752
79 + 513673 = 513752
103 + 513649 = 513752
223 + 513529 = 513752
241 + 513511 = 513752

Showing the first eight; more decompositions exist.
