Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162538, here are decompositions:

11 + 162527 = 162538
149 + 162389 = 162538
179 + 162359 = 162538
251 + 162287 = 162538
269 + 162269 = 162538
281 + 162257 = 162538
317 + 162221 = 162538
419 + 162119 = 162538

Showing the first eight; more decompositions exist.
