Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159438, here are decompositions:

7 + 159431 = 159438
17 + 159421 = 159438
31 + 159407 = 159438
89 + 159349 = 159438
101 + 159337 = 159438
127 + 159311 = 159438
151 + 159287 = 159438
211 + 159227 = 159438

Showing the first eight; more decompositions exist.
