Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17478, here are decompositions:

7 + 17471 = 17478
11 + 17467 = 17478
29 + 17449 = 17478
47 + 17431 = 17478
59 + 17419 = 17478
61 + 17417 = 17478
89 + 17389 = 17478
101 + 17377 = 17478

Showing the first eight; more decompositions exist.
