Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540444, here are decompositions:

7 + 540437 = 540444
11 + 540433 = 540444
53 + 540391 = 540444
61 + 540383 = 540444
67 + 540377 = 540444
71 + 540373 = 540444
97 + 540347 = 540444
101 + 540343 = 540444

Showing the first eight; more decompositions exist.
