Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700906, here are decompositions:

13 + 8700893 = 8700906
37 + 8700869 = 8700906
73 + 8700833 = 8700906
79 + 8700827 = 8700906
89 + 8700817 = 8700906
107 + 8700799 = 8700906
113 + 8700793 = 8700906
139 + 8700767 = 8700906

Showing the first eight; more decompositions exist.
