Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74838, here are decompositions:

7 + 74831 = 74838
11 + 74827 = 74838
17 + 74821 = 74838
41 + 74797 = 74838
59 + 74779 = 74838
67 + 74771 = 74838
79 + 74759 = 74838
107 + 74731 = 74838

Showing the first eight; more decompositions exist.
