Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540642, here are decompositions:

13 + 540629 = 540642
23 + 540619 = 540642
29 + 540613 = 540642
31 + 540611 = 540642
43 + 540599 = 540642
83 + 540559 = 540642
101 + 540541 = 540642
103 + 540539 = 540642

Showing the first eight; more decompositions exist.
