Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540390, here are decompositions:

7 + 540383 = 540390
13 + 540377 = 540390
17 + 540373 = 540390
23 + 540367 = 540390
41 + 540349 = 540390
43 + 540347 = 540390
47 + 540343 = 540390
83 + 540307 = 540390

Showing the first eight; more decompositions exist.
