Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709970, here are decompositions:

11 + 8709959 = 8709970
29 + 8709941 = 8709970
41 + 8709929 = 8709970
131 + 8709839 = 8709970
149 + 8709821 = 8709970
233 + 8709737 = 8709970
239 + 8709731 = 8709970
251 + 8709719 = 8709970

Showing the first eight; more decompositions exist.
