Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707906, here are decompositions:

3 + 8707903 = 8707906
23 + 8707883 = 8707906
29 + 8707877 = 8707906
89 + 8707817 = 8707906
113 + 8707793 = 8707906
257 + 8707649 = 8707906
563 + 8707343 = 8707906
617 + 8707289 = 8707906

Showing the first eight; more decompositions exist.
