Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105720, here are decompositions:

19 + 105701 = 105720
29 + 105691 = 105720
37 + 105683 = 105720
47 + 105673 = 105720
53 + 105667 = 105720
67 + 105653 = 105720
71 + 105649 = 105720
101 + 105619 = 105720

Showing the first eight; more decompositions exist.
