Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73142, here are decompositions:

79 + 73063 = 73142
103 + 73039 = 73142
193 + 72949 = 73142
211 + 72931 = 73142
241 + 72901 = 73142
271 + 72871 = 73142
283 + 72859 = 73142
379 + 72763 = 73142

Showing the first eight; more decompositions exist.
