Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127698, here are decompositions:

7 + 127691 = 127698
17 + 127681 = 127698
19 + 127679 = 127698
29 + 127669 = 127698
41 + 127657 = 127698
61 + 127637 = 127698
89 + 127609 = 127698
97 + 127601 = 127698

Showing the first eight; more decompositions exist.
