Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663906, here are decompositions:

7 + 8663899 = 8663906
37 + 8663869 = 8663906
79 + 8663827 = 8663906
103 + 8663803 = 8663906
109 + 8663797 = 8663906
313 + 8663593 = 8663906
397 + 8663509 = 8663906
409 + 8663497 = 8663906

Showing the first eight; more decompositions exist.
