Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17542, here are decompositions:

3 + 17539 = 17542
23 + 17519 = 17542
53 + 17489 = 17542
59 + 17483 = 17542
71 + 17471 = 17542
149 + 17393 = 17542
191 + 17351 = 17542
251 + 17291 = 17542

Showing the first eight; more decompositions exist.
