Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540530, here are decompositions:

13 + 540517 = 540530
19 + 540511 = 540530
61 + 540469 = 540530
97 + 540433 = 540530
139 + 540391 = 540530
157 + 540373 = 540530
163 + 540367 = 540530
181 + 540349 = 540530

Showing the first eight; more decompositions exist.
