Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972222, here are decompositions:

23 + 972199 = 972222
59 + 972163 = 972222
61 + 972161 = 972222
89 + 972133 = 972222
101 + 972121 = 972222
103 + 972119 = 972222
109 + 972113 = 972222
131 + 972091 = 972222

Showing the first eight; more decompositions exist.
