Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31146, here are decompositions:

7 + 31139 = 31146
23 + 31123 = 31146
67 + 31079 = 31146
83 + 31063 = 31146
107 + 31039 = 31146
113 + 31033 = 31146
127 + 31019 = 31146
163 + 30983 = 31146

Showing the first eight; more decompositions exist.
