Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127758, here are decompositions:

11 + 127747 = 127758
19 + 127739 = 127758
31 + 127727 = 127758
41 + 127717 = 127758
47 + 127711 = 127758
67 + 127691 = 127758
79 + 127679 = 127758
89 + 127669 = 127758

Showing the first eight; more decompositions exist.
