Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77142, here are decompositions:

5 + 77137 = 77142
41 + 77101 = 77142
61 + 77081 = 77142
73 + 77069 = 77142
101 + 77041 = 77142
113 + 77029 = 77142
139 + 77003 = 77142
151 + 76991 = 77142

Showing the first eight; more decompositions exist.
