Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945550, here are decompositions:

3 + 945547 = 945550
29 + 945521 = 945550
71 + 945479 = 945550
173 + 945377 = 945550
191 + 945359 = 945550
257 + 945293 = 945550
317 + 945233 = 945550
461 + 945089 = 945550

Showing the first eight; more decompositions exist.
