Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540618, here are decompositions:

5 + 540613 = 540618
7 + 540611 = 540618
19 + 540599 = 540618
31 + 540587 = 540618
41 + 540577 = 540618
59 + 540559 = 540618
61 + 540557 = 540618
79 + 540539 = 540618

Showing the first eight; more decompositions exist.
