Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637668, here are decompositions:

31 + 8637637 = 8637668
241 + 8637427 = 8637668
331 + 8637337 = 8637668
349 + 8637319 = 8637668
367 + 8637301 = 8637668
379 + 8637289 = 8637668
421 + 8637247 = 8637668
577 + 8637091 = 8637668

Showing the first eight; more decompositions exist.
