Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972280, here are decompositions:

3 + 972277 = 972280
17 + 972263 = 972280
53 + 972227 = 972280
59 + 972221 = 972280
83 + 972197 = 972280
149 + 972131 = 972280
167 + 972113 = 972280
233 + 972047 = 972280

Showing the first eight; more decompositions exist.
