Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709918, here are decompositions:

5 + 8709913 = 8709918
47 + 8709871 = 8709918
79 + 8709839 = 8709918
97 + 8709821 = 8709918
101 + 8709817 = 8709918
137 + 8709781 = 8709918
167 + 8709751 = 8709918
181 + 8709737 = 8709918

Showing the first eight; more decompositions exist.
