Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512444, here are decompositions:

157 + 512287 = 512444
193 + 512251 = 512444
277 + 512167 = 512444
307 + 512137 = 512444
397 + 512047 = 512444
433 + 512011 = 512444
547 + 511897 = 512444
571 + 511873 = 512444

Showing the first eight; more decompositions exist.
