Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139692, here are decompositions:

11 + 139681 = 139692
29 + 139663 = 139692
31 + 139661 = 139692
73 + 139619 = 139692
83 + 139609 = 139692
101 + 139591 = 139692
103 + 139589 = 139692
181 + 139511 = 139692

Showing the first eight; more decompositions exist.
