Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541906, here are decompositions:

5 + 541901 = 541906
17 + 541889 = 541906
47 + 541859 = 541906
89 + 541817 = 541906
107 + 541799 = 541906
179 + 541727 = 541906
293 + 541613 = 541906
317 + 541589 = 541906

Showing the first eight; more decompositions exist.
