Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140972, here are decompositions:

43 + 140929 = 140972
79 + 140893 = 140972
103 + 140869 = 140972
109 + 140863 = 140972
193 + 140779 = 140972
199 + 140773 = 140972
211 + 140761 = 140972
241 + 140731 = 140972

Showing the first eight; more decompositions exist.
