Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42856, here are decompositions:

3 + 42853 = 42856
17 + 42839 = 42856
59 + 42797 = 42856
83 + 42773 = 42856
89 + 42767 = 42856
113 + 42743 = 42856
137 + 42719 = 42856
167 + 42689 = 42856

Showing the first eight; more decompositions exist.
