Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23142, here are decompositions:

11 + 23131 = 23142
43 + 23099 = 23142
61 + 23081 = 23142
71 + 23071 = 23142
79 + 23063 = 23142
83 + 23059 = 23142
89 + 23053 = 23142
101 + 23041 = 23142

Showing the first eight; more decompositions exist.
