Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540572, here are decompositions:

13 + 540559 = 540572
31 + 540541 = 540572
61 + 540511 = 540572
103 + 540469 = 540572
139 + 540433 = 540572
181 + 540391 = 540572
199 + 540373 = 540572
223 + 540349 = 540572

Showing the first eight; more decompositions exist.
