Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42928, here are decompositions:

5 + 42923 = 42928
29 + 42899 = 42928
89 + 42839 = 42928
107 + 42821 = 42928
131 + 42797 = 42928
191 + 42737 = 42928
227 + 42701 = 42928
239 + 42689 = 42928

Showing the first eight; more decompositions exist.
