Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655250, here are decompositions:

53 + 8655197 = 8655250
83 + 8655167 = 8655250
101 + 8655149 = 8655250
179 + 8655071 = 8655250
239 + 8655011 = 8655250
269 + 8654981 = 8655250
353 + 8654897 = 8655250
479 + 8654771 = 8655250

Showing the first eight; more decompositions exist.
