Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65972, here are decompositions:

43 + 65929 = 65972
73 + 65899 = 65972
163 + 65809 = 65972
211 + 65761 = 65972
241 + 65731 = 65972
271 + 65701 = 65972
373 + 65599 = 65972
409 + 65563 = 65972

Showing the first eight; more decompositions exist.
