Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139452, here are decompositions:

13 + 139439 = 139452
23 + 139429 = 139452
29 + 139423 = 139452
43 + 139409 = 139452
59 + 139393 = 139452
83 + 139369 = 139452
109 + 139343 = 139452
113 + 139339 = 139452

Showing the first eight; more decompositions exist.
