Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57018, here are decompositions:

19 + 56999 = 57018
29 + 56989 = 57018
61 + 56957 = 57018
67 + 56951 = 57018
89 + 56929 = 57018
97 + 56921 = 57018
107 + 56911 = 57018
109 + 56909 = 57018

Showing the first eight; more decompositions exist.
