Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15356, here are decompositions:

7 + 15349 = 15356
37 + 15319 = 15356
43 + 15313 = 15356
67 + 15289 = 15356
79 + 15277 = 15356
97 + 15259 = 15356
139 + 15217 = 15356
157 + 15199 = 15356

Showing the first eight; more decompositions exist.
