Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509486, here are decompositions:

37 + 509449 = 509486
73 + 509413 = 509486
97 + 509389 = 509486
127 + 509359 = 509486
157 + 509329 = 509486
193 + 509293 = 509486
199 + 509287 = 509486
223 + 509263 = 509486

Showing the first eight; more decompositions exist.
