Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140444, here are decompositions:

37 + 140407 = 140444
43 + 140401 = 140444
127 + 140317 = 140444
163 + 140281 = 140444
181 + 140263 = 140444
223 + 140221 = 140444
277 + 140167 = 140444
373 + 140071 = 140444

Showing the first eight; more decompositions exist.
