Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735520, here are decompositions:

11 + 8735509 = 8735520
41 + 8735479 = 8735520
67 + 8735453 = 8735520
71 + 8735449 = 8735520
103 + 8735417 = 8735520
107 + 8735413 = 8735520
149 + 8735371 = 8735520
173 + 8735347 = 8735520

Showing the first eight; more decompositions exist.
