Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17142, here are decompositions:

5 + 17137 = 17142
19 + 17123 = 17142
43 + 17099 = 17142
89 + 17053 = 17142
101 + 17041 = 17142
109 + 17033 = 17142
113 + 17029 = 17142
131 + 17011 = 17142

Showing the first eight; more decompositions exist.
