Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127450, here are decompositions:

3 + 127447 = 127450
47 + 127403 = 127450
107 + 127343 = 127450
149 + 127301 = 127450
173 + 127277 = 127450
179 + 127271 = 127450
233 + 127217 = 127450
293 + 127157 = 127450

Showing the first eight; more decompositions exist.
