Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945378, here are decompositions:

11 + 945367 = 945378
19 + 945359 = 945378
29 + 945349 = 945378
37 + 945341 = 945378
47 + 945331 = 945378
89 + 945289 = 945378
151 + 945227 = 945378
167 + 945211 = 945378

Showing the first eight; more decompositions exist.
