Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709278, here are decompositions:

7 + 8709271 = 8709278
139 + 8709139 = 8709278
157 + 8709121 = 8709278
199 + 8709079 = 8709278
211 + 8709067 = 8709278
271 + 8709007 = 8709278
307 + 8708971 = 8709278
367 + 8708911 = 8709278

Showing the first eight; more decompositions exist.
