Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637404, here are decompositions:

31 + 8637373 = 8637404
67 + 8637337 = 8637404
103 + 8637301 = 8637404
151 + 8637253 = 8637404
157 + 8637247 = 8637404
241 + 8637163 = 8637404
271 + 8637133 = 8637404
313 + 8637091 = 8637404

Showing the first eight; more decompositions exist.
