Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162394, here are decompositions:

3 + 162391 = 162394
5 + 162389 = 162394
101 + 162293 = 162394
107 + 162287 = 162394
131 + 162263 = 162394
137 + 162257 = 162394
173 + 162221 = 162394
251 + 162143 = 162394

Showing the first eight; more decompositions exist.
