Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508986, here are decompositions:

13 + 508973 = 508986
17 + 508969 = 508986
29 + 508957 = 508986
43 + 508943 = 508986
67 + 508919 = 508986
73 + 508913 = 508986
83 + 508903 = 508986
139 + 508847 = 508986

Showing the first eight; more decompositions exist.
