Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640304, here are decompositions:

17 + 8640287 = 8640304
41 + 8640263 = 8640304
53 + 8640251 = 8640304
83 + 8640221 = 8640304
107 + 8640197 = 8640304
317 + 8639987 = 8640304
353 + 8639951 = 8640304
383 + 8639921 = 8640304

Showing the first eight; more decompositions exist.
