Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501870, here are decompositions:

7 + 501863 = 501870
29 + 501841 = 501870
41 + 501829 = 501870
43 + 501827 = 501870
53 + 501817 = 501870
67 + 501803 = 501870
101 + 501769 = 501870
139 + 501731 = 501870

Showing the first eight; more decompositions exist.
