Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505450, here are decompositions:

3 + 505447 = 505450
41 + 505409 = 505450
83 + 505367 = 505450
131 + 505319 = 505450
137 + 505313 = 505450
149 + 505301 = 505450
167 + 505283 = 505450
173 + 505277 = 505450

Showing the first eight; more decompositions exist.
