Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972818, here are decompositions:

19 + 972799 = 972818
31 + 972787 = 972818
97 + 972721 = 972818
139 + 972679 = 972818
157 + 972661 = 972818
181 + 972637 = 972818
241 + 972577 = 972818
337 + 972481 = 972818

Showing the first eight; more decompositions exist.
