Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709218, here are decompositions:

31 + 8709187 = 8709218
79 + 8709139 = 8709218
97 + 8709121 = 8709218
139 + 8709079 = 8709218
151 + 8709067 = 8709218
211 + 8709007 = 8709218
307 + 8708911 = 8709218
487 + 8708731 = 8709218

Showing the first eight; more decompositions exist.
