Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505372, here are decompositions:

3 + 505369 = 505372
5 + 505367 = 505372
53 + 505319 = 505372
59 + 505313 = 505372
71 + 505301 = 505372
89 + 505283 = 505372
191 + 505181 = 505372
233 + 505139 = 505372

Showing the first eight; more decompositions exist.
