Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972918, here are decompositions:

17 + 972901 = 972918
19 + 972899 = 972918
31 + 972887 = 972918
71 + 972847 = 972918
131 + 972787 = 972918
197 + 972721 = 972918
239 + 972679 = 972918
257 + 972661 = 972918

Showing the first eight; more decompositions exist.
