Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501418, here are decompositions:

17 + 501401 = 501418
101 + 501317 = 501418
131 + 501287 = 501418
227 + 501191 = 501418
389 + 501029 = 501418
461 + 500957 = 501418
509 + 500909 = 501418
557 + 500861 = 501418

Showing the first eight; more decompositions exist.
