Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637898, here are decompositions:

29 + 8637869 = 8637898
107 + 8637791 = 8637898
149 + 8637749 = 8637898
197 + 8637701 = 8637898
257 + 8637641 = 8637898
281 + 8637617 = 8637898
389 + 8637509 = 8637898
431 + 8637467 = 8637898

Showing the first eight; more decompositions exist.
