Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736400, here are decompositions:

59 + 8736341 = 8736400
137 + 8736263 = 8736400
191 + 8736209 = 8736400
227 + 8736173 = 8736400
311 + 8736089 = 8736400
359 + 8736041 = 8736400
467 + 8735933 = 8736400
503 + 8735897 = 8736400

Showing the first eight; more decompositions exist.
