Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509678, here are decompositions:

19 + 509659 = 509678
31 + 509647 = 509678
97 + 509581 = 509678
109 + 509569 = 509678
157 + 509521 = 509678
229 + 509449 = 509678
349 + 509329 = 509678
397 + 509281 = 509678

Showing the first eight; more decompositions exist.
