Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972828, here are decompositions:

5 + 972823 = 972828
29 + 972799 = 972828
41 + 972787 = 972828
107 + 972721 = 972828
127 + 972701 = 972828
149 + 972679 = 972828
167 + 972661 = 972828
179 + 972649 = 972828

Showing the first eight; more decompositions exist.
