Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540798, here are decompositions:

17 + 540781 = 540798
19 + 540779 = 540798
29 + 540769 = 540798
47 + 540751 = 540798
101 + 540697 = 540798
107 + 540691 = 540798
109 + 540689 = 540798
179 + 540619 = 540798

Showing the first eight; more decompositions exist.
