Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638060, here are decompositions:

17 + 8638043 = 8638060
107 + 8637953 = 8638060
131 + 8637929 = 8638060
191 + 8637869 = 8638060
239 + 8637821 = 8638060
269 + 8637791 = 8638060
281 + 8637779 = 8638060
311 + 8637749 = 8638060

Showing the first eight; more decompositions exist.
