Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001142, here are decompositions:

19 + 1001123 = 1001142
53 + 1001089 = 1001142
61 + 1001081 = 1001142
73 + 1001069 = 1001142
101 + 1001041 = 1001142
139 + 1001003 = 1001142
173 + 1000969 = 1001142
211 + 1000931 = 1001142

Showing the first eight; more decompositions exist.
