Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15402, here are decompositions:

11 + 15391 = 15402
19 + 15383 = 15402
29 + 15373 = 15402
41 + 15361 = 15402
43 + 15359 = 15402
53 + 15349 = 15402
71 + 15331 = 15402
73 + 15329 = 15402

Showing the first eight; more decompositions exist.
