Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657400, here are decompositions:

13 + 8657387 = 8657400
19 + 8657381 = 8657400
23 + 8657377 = 8657400
43 + 8657357 = 8657400
67 + 8657333 = 8657400
109 + 8657291 = 8657400
151 + 8657249 = 8657400
163 + 8657237 = 8657400

Showing the first eight; more decompositions exist.
