Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17456, here are decompositions:

7 + 17449 = 17456
13 + 17443 = 17456
37 + 17419 = 17456
67 + 17389 = 17456
73 + 17383 = 17456
79 + 17377 = 17456
97 + 17359 = 17456
139 + 17317 = 17456

Showing the first eight; more decompositions exist.
