Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653340, here are decompositions:

13 + 8653327 = 8653340
43 + 8653297 = 8653340
61 + 8653279 = 8653340
79 + 8653261 = 8653340
97 + 8653243 = 8653340
103 + 8653237 = 8653340
109 + 8653231 = 8653340
193 + 8653147 = 8653340

Showing the first eight; more decompositions exist.
