Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140738, here are decompositions:

7 + 140731 = 140738
61 + 140677 = 140738
79 + 140659 = 140738
109 + 140629 = 140738
127 + 140611 = 140738
151 + 140587 = 140738
181 + 140557 = 140738
211 + 140527 = 140738

Showing the first eight; more decompositions exist.
