Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127722, here are decompositions:

5 + 127717 = 127722
11 + 127711 = 127722
13 + 127709 = 127722
19 + 127703 = 127722
31 + 127691 = 127722
41 + 127681 = 127722
43 + 127679 = 127722
53 + 127669 = 127722

Showing the first eight; more decompositions exist.
