Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638098, here are decompositions:

31 + 8638067 = 8638098
37 + 8638061 = 8638098
47 + 8638051 = 8638098
59 + 8638039 = 8638098
107 + 8637991 = 8638098
229 + 8637869 = 8638098
251 + 8637847 = 8638098
269 + 8637829 = 8638098

Showing the first eight; more decompositions exist.
