Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607988, here are decompositions:

17 + 8607971 = 8607988
41 + 8607947 = 8607988
71 + 8607917 = 8607988
101 + 8607887 = 8607988
167 + 8607821 = 8607988
239 + 8607749 = 8607988
251 + 8607737 = 8607988
359 + 8607629 = 8607988

Showing the first eight; more decompositions exist.
