Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538690, here are decompositions:

41 + 538649 = 538690
101 + 538589 = 538690
137 + 538553 = 538690
167 + 538523 = 538690
179 + 538511 = 538690
233 + 538457 = 538690
293 + 538397 = 538690
359 + 538331 = 538690

Showing the first eight; more decompositions exist.
