Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15382, here are decompositions:

5 + 15377 = 15382
23 + 15359 = 15382
53 + 15329 = 15382
83 + 15299 = 15382
113 + 15269 = 15382
149 + 15233 = 15382
233 + 15149 = 15382
251 + 15131 = 15382

Showing the first eight; more decompositions exist.
