Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744450, here are decompositions:

3 + 8744447 = 8744450
31 + 8744419 = 8744450
37 + 8744413 = 8744450
181 + 8744269 = 8744450
223 + 8744227 = 8744450
307 + 8744143 = 8744450
349 + 8744101 = 8744450
367 + 8744083 = 8744450

Showing the first eight; more decompositions exist.
