Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640108, here are decompositions:

107 + 8640001 = 8640108
131 + 8639977 = 8640108
157 + 8639951 = 8640108
199 + 8639909 = 8640108
271 + 8639837 = 8640108
311 + 8639797 = 8640108
359 + 8639749 = 8640108
397 + 8639711 = 8640108

Showing the first eight; more decompositions exist.
