Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509972, here are decompositions:

13 + 509959 = 509972
61 + 509911 = 509972
109 + 509863 = 509972
139 + 509833 = 509972
241 + 509731 = 509972
283 + 509689 = 509972
313 + 509659 = 509972
349 + 509623 = 509972

Showing the first eight; more decompositions exist.
