Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540402, here are decompositions:

11 + 540391 = 540402
13 + 540389 = 540402
19 + 540383 = 540402
29 + 540373 = 540402
53 + 540349 = 540402
59 + 540343 = 540402
101 + 540301 = 540402
131 + 540271 = 540402

Showing the first eight; more decompositions exist.
