Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9542, here are decompositions:

3 + 9539 = 9542
31 + 9511 = 9542
79 + 9463 = 9542
103 + 9439 = 9542
109 + 9433 = 9542
139 + 9403 = 9542
151 + 9391 = 9542
193 + 9349 = 9542

Showing the first eight; more decompositions exist.
