Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42874, here are decompositions:

11 + 42863 = 42874
53 + 42821 = 42874
101 + 42773 = 42874
107 + 42767 = 42874
131 + 42743 = 42874
137 + 42737 = 42874
173 + 42701 = 42874
191 + 42683 = 42874

Showing the first eight; more decompositions exist.
