Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972440, here are decompositions:

13 + 972427 = 972440
31 + 972409 = 972440
37 + 972403 = 972440
67 + 972373 = 972440
97 + 972343 = 972440
103 + 972337 = 972440
127 + 972313 = 972440
163 + 972277 = 972440

Showing the first eight; more decompositions exist.
