Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972866, here are decompositions:

19 + 972847 = 972866
43 + 972823 = 972866
67 + 972799 = 972866
73 + 972793 = 972866
79 + 972787 = 972866
229 + 972637 = 972866
373 + 972493 = 972866
397 + 972469 = 972866

Showing the first eight; more decompositions exist.
