Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7142, here are decompositions:

13 + 7129 = 7142
73 + 7069 = 7142
103 + 7039 = 7142
151 + 6991 = 7142
181 + 6961 = 7142
193 + 6949 = 7142
271 + 6871 = 7142
313 + 6829 = 7142

Showing the first eight; more decompositions exist.
