Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972240, here are decompositions:

11 + 972229 = 972240
13 + 972227 = 972240
19 + 972221 = 972240
41 + 972199 = 972240
43 + 972197 = 972240
79 + 972161 = 972240
103 + 972137 = 972240
107 + 972133 = 972240

Showing the first eight; more decompositions exist.
