Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972806, here are decompositions:

7 + 972799 = 972806
13 + 972793 = 972806
19 + 972787 = 972806
127 + 972679 = 972806
157 + 972649 = 972806
193 + 972613 = 972806
229 + 972577 = 972806
313 + 972493 = 972806

Showing the first eight; more decompositions exist.
