Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972180, here are decompositions:

17 + 972163 = 972180
19 + 972161 = 972180
43 + 972137 = 972180
47 + 972133 = 972180
59 + 972121 = 972180
61 + 972119 = 972180
67 + 972113 = 972180
89 + 972091 = 972180

Showing the first eight; more decompositions exist.
