Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139890, here are decompositions:

7 + 139883 = 139890
19 + 139871 = 139890
29 + 139861 = 139890
53 + 139837 = 139890
59 + 139831 = 139890
89 + 139801 = 139890
103 + 139787 = 139890
131 + 139759 = 139890

Showing the first eight; more decompositions exist.
