Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130142, here are decompositions:

43 + 130099 = 130142
73 + 130069 = 130142
139 + 130003 = 130142
223 + 129919 = 130142
241 + 129901 = 130142
349 + 129793 = 130142
373 + 129769 = 130142
379 + 129763 = 130142

Showing the first eight; more decompositions exist.
