Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709904, here are decompositions:

83 + 8709821 = 8709904
167 + 8709737 = 8709904
173 + 8709731 = 8709904
191 + 8709713 = 8709904
227 + 8709677 = 8709904
251 + 8709653 = 8709904
257 + 8709647 = 8709904
293 + 8709611 = 8709904

Showing the first eight; more decompositions exist.
