Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540522, here are decompositions:

5 + 540517 = 540522
11 + 540511 = 540522
13 + 540509 = 540522
53 + 540469 = 540522
61 + 540461 = 540522
89 + 540433 = 540522
131 + 540391 = 540522
139 + 540383 = 540522

Showing the first eight; more decompositions exist.
