Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127518, here are decompositions:

11 + 127507 = 127518
31 + 127487 = 127518
37 + 127481 = 127518
71 + 127447 = 127518
197 + 127321 = 127518
227 + 127291 = 127518
229 + 127289 = 127518
241 + 127277 = 127518

Showing the first eight; more decompositions exist.
