Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501530, here are decompositions:

19 + 501511 = 501530
37 + 501493 = 501530
67 + 501463 = 501530
79 + 501451 = 501530
103 + 501427 = 501530
163 + 501367 = 501530
307 + 501223 = 501530
313 + 501217 = 501530

Showing the first eight; more decompositions exist.
