Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972188, here are decompositions:

67 + 972121 = 972188
97 + 972091 = 972188
109 + 972079 = 972188
157 + 972031 = 972188
199 + 971989 = 972188
211 + 971977 = 972188
229 + 971959 = 972188
271 + 971917 = 972188

Showing the first eight; more decompositions exist.
