Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972858, here are decompositions:

11 + 972847 = 972858
31 + 972827 = 972858
59 + 972799 = 972858
71 + 972787 = 972858
137 + 972721 = 972858
157 + 972701 = 972858
179 + 972679 = 972858
197 + 972661 = 972858

Showing the first eight; more decompositions exist.
