Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505444, here are decompositions:

131 + 505313 = 505444
167 + 505277 = 505444
257 + 505187 = 505444
263 + 505181 = 505444
347 + 505097 = 505444
353 + 505091 = 505444
383 + 505061 = 505444
461 + 504983 = 505444

Showing the first eight; more decompositions exist.
