Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739400, here are decompositions:

3 + 8739397 = 8739400
11 + 8739389 = 8739400
41 + 8739359 = 8739400
101 + 8739299 = 8739400
191 + 8739209 = 8739400
233 + 8739167 = 8739400
281 + 8739119 = 8739400
347 + 8739053 = 8739400

Showing the first eight; more decompositions exist.
