Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705450, here are decompositions:

7 + 8705443 = 8705450
31 + 8705419 = 8705450
67 + 8705383 = 8705450
139 + 8705311 = 8705450
151 + 8705299 = 8705450
181 + 8705269 = 8705450
283 + 8705167 = 8705450
373 + 8705077 = 8705450

Showing the first eight; more decompositions exist.
