Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541938, here are decompositions:

11 + 541927 = 541938
37 + 541901 = 541938
79 + 541859 = 541938
101 + 541837 = 541938
107 + 541831 = 541938
139 + 541799 = 541938
157 + 541781 = 541938
167 + 541771 = 541938

Showing the first eight; more decompositions exist.
