Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501840, here are decompositions:

11 + 501829 = 501840
13 + 501827 = 501840
19 + 501821 = 501840
23 + 501817 = 501840
37 + 501803 = 501840
61 + 501779 = 501840
71 + 501769 = 501840
109 + 501731 = 501840

Showing the first eight; more decompositions exist.
