Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508842, here are decompositions:

31 + 508811 = 508842
43 + 508799 = 508842
53 + 508789 = 508842
71 + 508771 = 508842
149 + 508693 = 508842
181 + 508661 = 508842
199 + 508643 = 508842
223 + 508619 = 508842

Showing the first eight; more decompositions exist.
