Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972878, here are decompositions:

31 + 972847 = 972878
79 + 972799 = 972878
157 + 972721 = 972878
199 + 972679 = 972878
229 + 972649 = 972878
241 + 972637 = 972878
397 + 972481 = 972878
409 + 972469 = 972878

Showing the first eight; more decompositions exist.
