Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640116, here are decompositions:

7 + 8640109 = 8640116
103 + 8640013 = 8640116
139 + 8639977 = 8640116
193 + 8639923 = 8640116
307 + 8639809 = 8640116
313 + 8639803 = 8640116
337 + 8639779 = 8640116
367 + 8639749 = 8640116

Showing the first eight; more decompositions exist.
