Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538946, here are decompositions:

3 + 538943 = 538946
7 + 538939 = 538946
19 + 538927 = 538946
157 + 538789 = 538946
223 + 538723 = 538946
349 + 538597 = 538946
367 + 538579 = 538946
379 + 538567 = 538946

Showing the first eight; more decompositions exist.
