Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637400, here are decompositions:

59 + 8637341 = 8637400
89 + 8637311 = 8637400
137 + 8637263 = 8637400
173 + 8637227 = 8637400
197 + 8637203 = 8637400
269 + 8637131 = 8637400
281 + 8637119 = 8637400
293 + 8637107 = 8637400

Showing the first eight; more decompositions exist.
