Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508900, here are decompositions:

53 + 508847 = 508900
59 + 508841 = 508900
83 + 508817 = 508900
89 + 508811 = 508900
101 + 508799 = 508900
173 + 508727 = 508900
191 + 508709 = 508900
239 + 508661 = 508900

Showing the first eight; more decompositions exist.
