Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945478, here are decompositions:

5 + 945473 = 945478
47 + 945431 = 945478
89 + 945389 = 945478
101 + 945377 = 945478
137 + 945341 = 945478
251 + 945227 = 945478
269 + 945209 = 945478
389 + 945089 = 945478

Showing the first eight; more decompositions exist.
