Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127130, here are decompositions:

7 + 127123 = 127130
79 + 127051 = 127130
97 + 127033 = 127130
163 + 126967 = 127130
181 + 126949 = 127130
271 + 126859 = 127130
307 + 126823 = 127130
349 + 126781 = 127130

Showing the first eight; more decompositions exist.
