Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509456, here are decompositions:

7 + 509449 = 509456
43 + 509413 = 509456
67 + 509389 = 509456
97 + 509359 = 509456
127 + 509329 = 509456
139 + 509317 = 509456
163 + 509293 = 509456
193 + 509263 = 509456

Showing the first eight; more decompositions exist.
