Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540640, here are decompositions:

11 + 540629 = 540640
29 + 540611 = 540640
41 + 540599 = 540640
53 + 540587 = 540640
83 + 540557 = 540640
101 + 540539 = 540640
131 + 540509 = 540640
179 + 540461 = 540640

Showing the first eight; more decompositions exist.
