Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42920, here are decompositions:

19 + 42901 = 42920
61 + 42859 = 42920
67 + 42853 = 42920
79 + 42841 = 42920
127 + 42793 = 42920
193 + 42727 = 42920
211 + 42709 = 42920
223 + 42697 = 42920

Showing the first eight; more decompositions exist.
