Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640312, here are decompositions:

53 + 8640259 = 8640312
61 + 8640251 = 8640312
71 + 8640241 = 8640312
101 + 8640211 = 8640312
151 + 8640161 = 8640312
179 + 8640133 = 8640312
311 + 8640001 = 8640312
389 + 8639923 = 8640312

Showing the first eight; more decompositions exist.
