Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709988, here are decompositions:

17 + 8709971 = 8709988
29 + 8709959 = 8709988
47 + 8709941 = 8709988
59 + 8709929 = 8709988
149 + 8709839 = 8709988
167 + 8709821 = 8709988
251 + 8709737 = 8709988
257 + 8709731 = 8709988

Showing the first eight; more decompositions exist.
