Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509664, here are decompositions:

5 + 509659 = 509664
11 + 509653 = 509664
17 + 509647 = 509664
31 + 509633 = 509664
41 + 509623 = 509664
61 + 509603 = 509664
73 + 509591 = 509664
83 + 509581 = 509664

Showing the first eight; more decompositions exist.
