Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9142, here are decompositions:

5 + 9137 = 9142
83 + 9059 = 9142
101 + 9041 = 9142
113 + 9029 = 9142
131 + 9011 = 9142
173 + 8969 = 9142
179 + 8963 = 9142
191 + 8951 = 9142

Showing the first eight; more decompositions exist.
