Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31142, here are decompositions:

3 + 31139 = 31142
19 + 31123 = 31142
61 + 31081 = 31142
73 + 31069 = 31142
79 + 31063 = 31142
103 + 31039 = 31142
109 + 31033 = 31142
193 + 30949 = 31142

Showing the first eight; more decompositions exist.
