Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972144, here are decompositions:

7 + 972137 = 972144
11 + 972133 = 972144
13 + 972131 = 972144
23 + 972121 = 972144
31 + 972113 = 972144
53 + 972091 = 972144
73 + 972071 = 972144
97 + 972047 = 972144

Showing the first eight; more decompositions exist.
