Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000142, here are decompositions:

43 + 1000099 = 1000142
61 + 1000081 = 1000142
103 + 1000039 = 1000142
109 + 1000033 = 1000142
139 + 1000003 = 1000142
163 + 999979 = 1000142
181 + 999961 = 1000142
211 + 999931 = 1000142

Showing the first eight; more decompositions exist.
