Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15480, here are decompositions:

7 + 15473 = 15480
13 + 15467 = 15480
19 + 15461 = 15480
29 + 15451 = 15480
37 + 15443 = 15480
41 + 15439 = 15480
53 + 15427 = 15480
67 + 15413 = 15480

Showing the first eight; more decompositions exist.
