Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38918, here are decompositions:

67 + 38851 = 38918
79 + 38839 = 38918
97 + 38821 = 38918
127 + 38791 = 38918
151 + 38767 = 38918
181 + 38737 = 38918
211 + 38707 = 38918
241 + 38677 = 38918

Showing the first eight; more decompositions exist.
