Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140628, here are decompositions:

11 + 140617 = 140628
17 + 140611 = 140628
41 + 140587 = 140628
71 + 140557 = 140628
79 + 140549 = 140628
101 + 140527 = 140628
107 + 140521 = 140628
151 + 140477 = 140628

Showing the first eight; more decompositions exist.
