Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508890, here are decompositions:

23 + 508867 = 508890
43 + 508847 = 508890
73 + 508817 = 508890
79 + 508811 = 508890
101 + 508789 = 508890
163 + 508727 = 508890
181 + 508709 = 508890
197 + 508693 = 508890

Showing the first eight; more decompositions exist.
