Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540690, here are decompositions:

11 + 540679 = 540690
13 + 540677 = 540690
61 + 540629 = 540690
71 + 540619 = 540690
79 + 540611 = 540690
103 + 540587 = 540690
113 + 540577 = 540690
131 + 540559 = 540690

Showing the first eight; more decompositions exist.
