Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640112, here are decompositions:

3 + 8640109 = 8640112
53 + 8640059 = 8640112
191 + 8639921 = 8640112
263 + 8639849 = 8640112
293 + 8639819 = 8640112
359 + 8639753 = 8640112
401 + 8639711 = 8640112
449 + 8639663 = 8640112

Showing the first eight; more decompositions exist.
