Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140636, here are decompositions:

7 + 140629 = 140636
19 + 140617 = 140636
43 + 140593 = 140636
79 + 140557 = 140636
103 + 140533 = 140636
109 + 140527 = 140636
163 + 140473 = 140636
193 + 140443 = 140636

Showing the first eight; more decompositions exist.
