Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501628, here are decompositions:

5 + 501623 = 501628
11 + 501617 = 501628
227 + 501401 = 501628
311 + 501317 = 501628
419 + 501209 = 501628
431 + 501197 = 501628
599 + 501029 = 501628
719 + 500909 = 501628

Showing the first eight; more decompositions exist.
