Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42992, here are decompositions:

3 + 42989 = 42992
13 + 42979 = 42992
31 + 42961 = 42992
139 + 42853 = 42992
151 + 42841 = 42992
163 + 42829 = 42992
199 + 42793 = 42992
241 + 42751 = 42992

Showing the first eight; more decompositions exist.
