Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640088, here are decompositions:

29 + 8640059 = 8640088
71 + 8640017 = 8640088
101 + 8639987 = 8640088
137 + 8639951 = 8640088
167 + 8639921 = 8640088
179 + 8639909 = 8640088
239 + 8639849 = 8640088
251 + 8639837 = 8640088

Showing the first eight; more decompositions exist.
