Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501536, here are decompositions:

43 + 501493 = 501536
73 + 501463 = 501536
109 + 501427 = 501536
127 + 501409 = 501536
193 + 501343 = 501536
307 + 501229 = 501536
313 + 501223 = 501536
349 + 501187 = 501536

Showing the first eight; more decompositions exist.
