Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127230, here are decompositions:

11 + 127219 = 127230
13 + 127217 = 127230
23 + 127207 = 127230
41 + 127189 = 127230
67 + 127163 = 127230
73 + 127157 = 127230
97 + 127133 = 127230
107 + 127123 = 127230

Showing the first eight; more decompositions exist.
