Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508906, here are decompositions:

3 + 508903 = 508906
5 + 508901 = 508906
59 + 508847 = 508906
89 + 508817 = 508906
107 + 508799 = 508906
179 + 508727 = 508906
197 + 508709 = 508906
263 + 508643 = 508906

Showing the first eight; more decompositions exist.
