Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139758, here are decompositions:

5 + 139753 = 139758
11 + 139747 = 139758
19 + 139739 = 139758
29 + 139729 = 139758
37 + 139721 = 139758
61 + 139697 = 139758
97 + 139661 = 139758
131 + 139627 = 139758

Showing the first eight; more decompositions exist.
