Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621450, here are decompositions:

7 + 8621443 = 8621450
37 + 8621413 = 8621450
73 + 8621377 = 8621450
151 + 8621299 = 8621450
241 + 8621209 = 8621450
307 + 8621143 = 8621450
349 + 8621101 = 8621450
367 + 8621083 = 8621450

Showing the first eight; more decompositions exist.
