Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951440, here are decompositions:

3 + 951437 = 951440
13 + 951427 = 951440
67 + 951373 = 951440
73 + 951367 = 951440
79 + 951361 = 951440
97 + 951343 = 951440
109 + 951331 = 951440
157 + 951283 = 951440

Showing the first eight; more decompositions exist.
