Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42442, here are decompositions:

5 + 42437 = 42442
83 + 42359 = 42442
149 + 42293 = 42442
233 + 42209 = 42442
263 + 42179 = 42442
311 + 42131 = 42442
353 + 42089 = 42442
359 + 42083 = 42442

Showing the first eight; more decompositions exist.
