Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126432, here are decompositions:

11 + 126421 = 126432
73 + 126359 = 126432
83 + 126349 = 126432
109 + 126323 = 126432
191 + 126241 = 126432
199 + 126233 = 126432
233 + 126199 = 126432
281 + 126151 = 126432

Showing the first eight; more decompositions exist.
