Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513690, here are decompositions:

7 + 513683 = 513690
11 + 513679 = 513690
17 + 513673 = 513690
41 + 513649 = 513690
59 + 513631 = 513690
97 + 513593 = 513690
157 + 513533 = 513690
179 + 513511 = 513690

Showing the first eight; more decompositions exist.
