Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68142, here are decompositions:

29 + 68113 = 68142
31 + 68111 = 68142
43 + 68099 = 68142
71 + 68071 = 68142
83 + 68059 = 68142
89 + 68053 = 68142
101 + 68041 = 68142
149 + 67993 = 68142

Showing the first eight; more decompositions exist.
