Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508690, here are decompositions:

29 + 508661 = 508690
47 + 508643 = 508690
53 + 508637 = 508690
71 + 508619 = 508690
107 + 508583 = 508690
113 + 508577 = 508690
131 + 508559 = 508690
173 + 508517 = 508690

Showing the first eight; more decompositions exist.
