Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74142, here are decompositions:

11 + 74131 = 74142
41 + 74101 = 74142
43 + 74099 = 74142
71 + 74071 = 74142
181 + 73961 = 74142
191 + 73951 = 74142
199 + 73943 = 74142
283 + 73859 = 74142

Showing the first eight; more decompositions exist.
