Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541540, here are decompositions:

3 + 541537 = 541540
11 + 541529 = 541540
17 + 541523 = 541540
29 + 541511 = 541540
71 + 541469 = 541540
101 + 541439 = 541540
149 + 541391 = 541540
179 + 541361 = 541540

Showing the first eight; more decompositions exist.
