Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645260, here are decompositions:

3 + 8645257 = 8645260
17 + 8645243 = 8645260
23 + 8645237 = 8645260
137 + 8645123 = 8645260
179 + 8645081 = 8645260
251 + 8645009 = 8645260
269 + 8644991 = 8645260
311 + 8644949 = 8645260

Showing the first eight; more decompositions exist.
