Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709284, here are decompositions:

13 + 8709271 = 8709284
97 + 8709187 = 8709284
151 + 8709133 = 8709284
163 + 8709121 = 8709284
277 + 8709007 = 8709284
313 + 8708971 = 8709284
373 + 8708911 = 8709284
673 + 8708611 = 8709284

Showing the first eight; more decompositions exist.
