Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972212, here are decompositions:

13 + 972199 = 972212
79 + 972133 = 972212
181 + 972031 = 972212
211 + 972001 = 972212
223 + 971989 = 972212
313 + 971899 = 972212
349 + 971863 = 972212
379 + 971833 = 972212

Showing the first eight; more decompositions exist.
