Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140978, here are decompositions:

109 + 140869 = 140978
139 + 140839 = 140978
151 + 140827 = 140978
181 + 140797 = 140978
199 + 140779 = 140978
349 + 140629 = 140978
367 + 140611 = 140978
421 + 140557 = 140978

Showing the first eight; more decompositions exist.
