Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540684, here are decompositions:

5 + 540679 = 540684
7 + 540677 = 540684
71 + 540613 = 540684
73 + 540611 = 540684
97 + 540587 = 540684
107 + 540577 = 540684
127 + 540557 = 540684
167 + 540517 = 540684

Showing the first eight; more decompositions exist.
