Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15354, here are decompositions:

5 + 15349 = 15354
23 + 15331 = 15354
41 + 15313 = 15354
47 + 15307 = 15354
67 + 15287 = 15354
83 + 15271 = 15354
113 + 15241 = 15354
127 + 15227 = 15354

Showing the first eight; more decompositions exist.
