Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139632, here are decompositions:

5 + 139627 = 139632
13 + 139619 = 139632
23 + 139609 = 139632
41 + 139591 = 139632
43 + 139589 = 139632
61 + 139571 = 139632
131 + 139501 = 139632
139 + 139493 = 139632

Showing the first eight; more decompositions exist.
