Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945400, here are decompositions:

3 + 945397 = 945400
11 + 945389 = 945400
23 + 945377 = 945400
41 + 945359 = 945400
59 + 945341 = 945400
107 + 945293 = 945400
167 + 945233 = 945400
173 + 945227 = 945400

Showing the first eight; more decompositions exist.
