Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640294, here are decompositions:

7 + 8640287 = 8640294
31 + 8640263 = 8640294
43 + 8640251 = 8640294
53 + 8640241 = 8640294
73 + 8640221 = 8640294
83 + 8640211 = 8640294
97 + 8640197 = 8640294
107 + 8640187 = 8640294

Showing the first eight; more decompositions exist.
