Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640358, here are decompositions:

29 + 8640329 = 8640358
71 + 8640287 = 8640358
107 + 8640251 = 8640358
137 + 8640221 = 8640358
197 + 8640161 = 8640358
449 + 8639909 = 8640358
509 + 8639849 = 8640358
521 + 8639837 = 8640358

Showing the first eight; more decompositions exist.
