Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103542, here are decompositions:

13 + 103529 = 103542
31 + 103511 = 103542
59 + 103483 = 103542
71 + 103471 = 103542
149 + 103393 = 103542
151 + 103391 = 103542
193 + 103349 = 103542
223 + 103319 = 103542

Showing the first eight; more decompositions exist.
