Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690988, here are decompositions:

17 + 8690971 = 8690988
29 + 8690959 = 8690988
37 + 8690951 = 8690988
41 + 8690947 = 8690988
67 + 8690921 = 8690988
71 + 8690917 = 8690988
167 + 8690821 = 8690988
191 + 8690797 = 8690988

Showing the first eight; more decompositions exist.
