Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540394, here are decompositions:

3 + 540391 = 540394
5 + 540389 = 540394
11 + 540383 = 540394
17 + 540377 = 540394
47 + 540347 = 540394
191 + 540203 = 540394
227 + 540167 = 540394
293 + 540101 = 540394

Showing the first eight; more decompositions exist.
