Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646652, here are decompositions:

71 + 8646581 = 8646652
149 + 8646503 = 8646652
173 + 8646479 = 8646652
251 + 8646401 = 8646652
263 + 8646389 = 8646652
353 + 8646299 = 8646652
359 + 8646293 = 8646652
383 + 8646269 = 8646652

Showing the first eight; more decompositions exist.
