Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15462, here are decompositions:

11 + 15451 = 15462
19 + 15443 = 15462
23 + 15439 = 15462
61 + 15401 = 15462
71 + 15391 = 15462
79 + 15383 = 15462
89 + 15373 = 15462
101 + 15361 = 15462

Showing the first eight; more decompositions exist.
