Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659144, here are decompositions:

23 + 8659121 = 8659144
47 + 8659097 = 8659144
83 + 8659061 = 8659144
101 + 8659043 = 8659144
107 + 8659037 = 8659144
167 + 8658977 = 8659144
233 + 8658911 = 8659144
251 + 8658893 = 8659144

Showing the first eight; more decompositions exist.
