Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127020, here are decompositions:

31 + 126989 = 127020
53 + 126967 = 127020
59 + 126961 = 127020
71 + 126949 = 127020
97 + 126923 = 127020
107 + 126913 = 127020
163 + 126857 = 127020
181 + 126839 = 127020

Showing the first eight; more decompositions exist.
