Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640246, here are decompositions:

5 + 8640241 = 8640246
59 + 8640187 = 8640246
113 + 8640133 = 8640246
137 + 8640109 = 8640246
229 + 8640017 = 8640246
233 + 8640013 = 8640246
269 + 8639977 = 8640246
337 + 8639909 = 8640246

Showing the first eight; more decompositions exist.
