Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140556, here are decompositions:

5 + 140551 = 140556
7 + 140549 = 140556
23 + 140533 = 140556
29 + 140527 = 140556
79 + 140477 = 140556
83 + 140473 = 140556
103 + 140453 = 140556
107 + 140449 = 140556

Showing the first eight; more decompositions exist.
