Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509450, here are decompositions:

37 + 509413 = 509450
61 + 509389 = 509450
157 + 509293 = 509450
163 + 509287 = 509450
211 + 509239 = 509450
223 + 509227 = 509450
229 + 509221 = 509450
313 + 509137 = 509450

Showing the first eight; more decompositions exist.
