Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945628, here are decompositions:

41 + 945587 = 945628
107 + 945521 = 945628
149 + 945479 = 945628
197 + 945431 = 945628
239 + 945389 = 945628
251 + 945377 = 945628
269 + 945359 = 945628
401 + 945227 = 945628

Showing the first eight; more decompositions exist.
