Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972218, here are decompositions:

19 + 972199 = 972218
97 + 972121 = 972218
127 + 972091 = 972218
139 + 972079 = 972218
229 + 971989 = 972218
241 + 971977 = 972218
367 + 971851 = 972218
397 + 971821 = 972218

Showing the first eight; more decompositions exist.
