Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640136, here are decompositions:

3 + 8640133 = 8640136
149 + 8639987 = 8640136
227 + 8639909 = 8640136
233 + 8639903 = 8640136
317 + 8639819 = 8640136
383 + 8639753 = 8640136
389 + 8639747 = 8640136
569 + 8639567 = 8640136

Showing the first eight; more decompositions exist.
