Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972420, here are decompositions:

11 + 972409 = 972420
13 + 972407 = 972420
17 + 972403 = 972420
47 + 972373 = 972420
67 + 972353 = 972420
73 + 972347 = 972420
83 + 972337 = 972420
101 + 972319 = 972420

Showing the first eight; more decompositions exist.
