Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75838, here are decompositions:

5 + 75833 = 75838
17 + 75821 = 75838
41 + 75797 = 75838
71 + 75767 = 75838
107 + 75731 = 75838
131 + 75707 = 75838
149 + 75689 = 75838
179 + 75659 = 75838

Showing the first eight; more decompositions exist.
