Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15392, here are decompositions:

19 + 15373 = 15392
31 + 15361 = 15392
43 + 15349 = 15392
61 + 15331 = 15392
73 + 15319 = 15392
79 + 15313 = 15392
103 + 15289 = 15392
151 + 15241 = 15392

Showing the first eight; more decompositions exist.
