Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006450, here are decompositions:

17 + 1006433 = 1006450
59 + 1006391 = 1006450
83 + 1006367 = 1006450
89 + 1006361 = 1006450
113 + 1006337 = 1006450
149 + 1006301 = 1006450
197 + 1006253 = 1006450
233 + 1006217 = 1006450

Showing the first eight; more decompositions exist.
