Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653240, here are decompositions:

3 + 8653237 = 8653240
41 + 8653199 = 8653240
83 + 8653157 = 8653240
137 + 8653103 = 8653240
269 + 8652971 = 8653240
293 + 8652947 = 8653240
311 + 8652929 = 8653240
353 + 8652887 = 8653240

Showing the first eight; more decompositions exist.
