Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540920, here are decompositions:

13 + 540907 = 540920
19 + 540901 = 540920
43 + 540877 = 540920
97 + 540823 = 540920
139 + 540781 = 540920
151 + 540769 = 540920
223 + 540697 = 540920
229 + 540691 = 540920

Showing the first eight; more decompositions exist.
