Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42808, here are decompositions:

11 + 42797 = 42808
41 + 42767 = 42808
71 + 42737 = 42808
89 + 42719 = 42808
107 + 42701 = 42808
131 + 42677 = 42808
167 + 42641 = 42808
197 + 42611 = 42808

Showing the first eight; more decompositions exist.
