Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687964, here are decompositions:

11 + 8687953 = 8687964
41 + 8687923 = 8687964
53 + 8687911 = 8687964
73 + 8687891 = 8687964
83 + 8687881 = 8687964
137 + 8687827 = 8687964
167 + 8687797 = 8687964
193 + 8687771 = 8687964

Showing the first eight; more decompositions exist.
