Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945538, here are decompositions:

17 + 945521 = 945538
59 + 945479 = 945538
107 + 945431 = 945538
149 + 945389 = 945538
179 + 945359 = 945538
197 + 945341 = 945538
311 + 945227 = 945538
359 + 945179 = 945538

Showing the first eight; more decompositions exist.
