Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717906, here are decompositions:

37 + 8717869 = 8717906
97 + 8717809 = 8717906
103 + 8717803 = 8717906
139 + 8717767 = 8717906
157 + 8717749 = 8717906
163 + 8717743 = 8717906
229 + 8717677 = 8717906
283 + 8717623 = 8717906

Showing the first eight; more decompositions exist.
