Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951680, here are decompositions:

31 + 951649 = 951680
43 + 951637 = 951680
97 + 951583 = 951680
109 + 951571 = 951680
127 + 951553 = 951680
211 + 951469 = 951680
307 + 951373 = 951680
313 + 951367 = 951680

Showing the first eight; more decompositions exist.
