Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127746, here are decompositions:

7 + 127739 = 127746
13 + 127733 = 127746
19 + 127727 = 127746
29 + 127717 = 127746
37 + 127709 = 127746
43 + 127703 = 127746
67 + 127679 = 127746
83 + 127663 = 127746

Showing the first eight; more decompositions exist.
