Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71942, here are decompositions:

43 + 71899 = 71942
61 + 71881 = 71942
181 + 71761 = 71942
223 + 71719 = 71942
229 + 71713 = 71942
271 + 71671 = 71942
349 + 71593 = 71942
373 + 71569 = 71942

Showing the first eight; more decompositions exist.
