Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140526, here are decompositions:

5 + 140521 = 140526
53 + 140473 = 140526
73 + 140453 = 140526
83 + 140443 = 140526
103 + 140423 = 140526
107 + 140419 = 140526
109 + 140417 = 140526
163 + 140363 = 140526

Showing the first eight; more decompositions exist.
