Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972628, here are decompositions:

5 + 972623 = 972628
17 + 972611 = 972628
29 + 972599 = 972628
47 + 972581 = 972628
71 + 972557 = 972628
197 + 972431 = 972628
281 + 972347 = 972628
401 + 972227 = 972628

Showing the first eight; more decompositions exist.
