Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665906, here are decompositions:

17 + 8665889 = 8665906
89 + 8665817 = 8665906
107 + 8665799 = 8665906
239 + 8665667 = 8665906
257 + 8665649 = 8665906
593 + 8665313 = 8665906
647 + 8665259 = 8665906
653 + 8665253 = 8665906

Showing the first eight; more decompositions exist.
