Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660890, here are decompositions:

3 + 8660887 = 8660890
71 + 8660819 = 8660890
137 + 8660753 = 8660890
149 + 8660741 = 8660890
167 + 8660723 = 8660890
191 + 8660699 = 8660890
197 + 8660693 = 8660890
233 + 8660657 = 8660890

Showing the first eight; more decompositions exist.
