Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621400, here are decompositions:

23 + 8621377 = 8621400
61 + 8621339 = 8621400
101 + 8621299 = 8621400
157 + 8621243 = 8621400
163 + 8621237 = 8621400
191 + 8621209 = 8621400
199 + 8621201 = 8621400
211 + 8621189 = 8621400

Showing the first eight; more decompositions exist.
