Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509478, here are decompositions:

29 + 509449 = 509478
37 + 509441 = 509478
61 + 509417 = 509478
89 + 509389 = 509478
149 + 509329 = 509478
181 + 509297 = 509478
191 + 509287 = 509478
197 + 509281 = 509478

Showing the first eight; more decompositions exist.
