Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12746, here are decompositions:

3 + 12743 = 12746
7 + 12739 = 12746
43 + 12703 = 12746
109 + 12637 = 12746
127 + 12619 = 12746
157 + 12589 = 12746
163 + 12583 = 12746
193 + 12553 = 12746

Showing the first eight; more decompositions exist.
