Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42828, here are decompositions:

7 + 42821 = 42828
31 + 42797 = 42828
41 + 42787 = 42828
61 + 42767 = 42828
101 + 42727 = 42828
109 + 42719 = 42828
127 + 42701 = 42828
131 + 42697 = 42828

Showing the first eight; more decompositions exist.
