Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972988, here are decompositions:

11 + 972977 = 972988
47 + 972941 = 972988
89 + 972899 = 972988
101 + 972887 = 972988
389 + 972599 = 972988
431 + 972557 = 972988
557 + 972431 = 972988
641 + 972347 = 972988

Showing the first eight; more decompositions exist.
