Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15746, here are decompositions:

7 + 15739 = 15746
13 + 15733 = 15746
19 + 15727 = 15746
67 + 15679 = 15746
79 + 15667 = 15746
97 + 15649 = 15746
103 + 15643 = 15746
127 + 15619 = 15746

Showing the first eight; more decompositions exist.
