Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619400, here are decompositions:

3 + 8619397 = 8619400
47 + 8619353 = 8619400
131 + 8619269 = 8619400
137 + 8619263 = 8619400
233 + 8619167 = 8619400
269 + 8619131 = 8619400
347 + 8619053 = 8619400
359 + 8619041 = 8619400

Showing the first eight; more decompositions exist.
