Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541138, here are decompositions:

5 + 541133 = 541138
41 + 541097 = 541138
89 + 541049 = 541138
131 + 541007 = 541138
137 + 541001 = 541138
149 + 540989 = 541138
359 + 540779 = 541138
449 + 540689 = 541138

Showing the first eight; more decompositions exist.
