Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17442, here are decompositions:

11 + 17431 = 17442
23 + 17419 = 17442
41 + 17401 = 17442
53 + 17389 = 17442
59 + 17383 = 17442
83 + 17359 = 17442
101 + 17341 = 17442
109 + 17333 = 17442

Showing the first eight; more decompositions exist.
