Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972228, here are decompositions:

7 + 972221 = 972228
29 + 972199 = 972228
31 + 972197 = 972228
67 + 972161 = 972228
97 + 972131 = 972228
107 + 972121 = 972228
109 + 972119 = 972228
137 + 972091 = 972228

Showing the first eight; more decompositions exist.
