Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15394, here are decompositions:

3 + 15391 = 15394
11 + 15383 = 15394
17 + 15377 = 15394
107 + 15287 = 15394
131 + 15263 = 15394
167 + 15227 = 15394
233 + 15161 = 15394
257 + 15137 = 15394

Showing the first eight; more decompositions exist.
