Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964728, here are decompositions:

7 + 964721 = 964728
31 + 964697 = 964728
67 + 964661 = 964728
139 + 964589 = 964728
151 + 964577 = 964728
157 + 964571 = 964728
197 + 964531 = 964728
211 + 964517 = 964728

Showing the first eight; more decompositions exist.
