Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56838, here are decompositions:

11 + 56827 = 56838
17 + 56821 = 56838
29 + 56809 = 56838
31 + 56807 = 56838
59 + 56779 = 56838
71 + 56767 = 56838
101 + 56737 = 56838
107 + 56731 = 56838

Showing the first eight; more decompositions exist.
