Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140588, here are decompositions:

31 + 140557 = 140588
37 + 140551 = 140588
61 + 140527 = 140588
67 + 140521 = 140588
139 + 140449 = 140588
181 + 140407 = 140588
271 + 140317 = 140588
307 + 140281 = 140588

Showing the first eight; more decompositions exist.
