Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127644, here are decompositions:

7 + 127637 = 127644
37 + 127607 = 127644
43 + 127601 = 127644
47 + 127597 = 127644
53 + 127591 = 127644
61 + 127583 = 127644
103 + 127541 = 127644
137 + 127507 = 127644

Showing the first eight; more decompositions exist.
