Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637698, here are decompositions:

31 + 8637667 = 8637698
61 + 8637637 = 8637698
79 + 8637619 = 8637698
271 + 8637427 = 8637698
379 + 8637319 = 8637698
397 + 8637301 = 8637698
409 + 8637289 = 8637698
547 + 8637151 = 8637698

Showing the first eight; more decompositions exist.
