Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538906, here are decompositions:

29 + 538877 = 538906
83 + 538823 = 538906
89 + 538817 = 538906
107 + 538799 = 538906
167 + 538739 = 538906
197 + 538709 = 538906
257 + 538649 = 538906
317 + 538589 = 538906

Showing the first eight; more decompositions exist.
