Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751664, here are decompositions:

71 + 8751593 = 8751664
101 + 8751563 = 8751664
107 + 8751557 = 8751664
137 + 8751527 = 8751664
197 + 8751467 = 8751664
263 + 8751401 = 8751664
293 + 8751371 = 8751664
431 + 8751233 = 8751664

Showing the first eight; more decompositions exist.
