Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640270, here are decompositions:

7 + 8640263 = 8640270
11 + 8640259 = 8640270
19 + 8640251 = 8640270
29 + 8640241 = 8640270
59 + 8640211 = 8640270
73 + 8640197 = 8640270
83 + 8640187 = 8640270
101 + 8640169 = 8640270

Showing the first eight; more decompositions exist.
