Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687740, here are decompositions:

11 + 8687729 = 8687740
41 + 8687699 = 8687740
53 + 8687687 = 8687740
71 + 8687669 = 8687740
137 + 8687603 = 8687740
227 + 8687513 = 8687740
263 + 8687477 = 8687740
311 + 8687429 = 8687740

Showing the first eight; more decompositions exist.
