Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501888, here are decompositions:

47 + 501841 = 501888
59 + 501829 = 501888
61 + 501827 = 501888
67 + 501821 = 501888
71 + 501817 = 501888
109 + 501779 = 501888
157 + 501731 = 501888
181 + 501707 = 501888

Showing the first eight; more decompositions exist.
