Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645400, here are decompositions:

19 + 8645381 = 8645400
41 + 8645359 = 8645400
47 + 8645353 = 8645400
59 + 8645341 = 8645400
73 + 8645327 = 8645400
107 + 8645293 = 8645400
131 + 8645269 = 8645400
139 + 8645261 = 8645400

Showing the first eight; more decompositions exist.
