Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741928, here are decompositions:

5 + 8741923 = 8741928
17 + 8741911 = 8741928
61 + 8741867 = 8741928
67 + 8741861 = 8741928
89 + 8741839 = 8741928
127 + 8741801 = 8741928
131 + 8741797 = 8741928
149 + 8741779 = 8741928

Showing the first eight; more decompositions exist.
