Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139466, here are decompositions:

7 + 139459 = 139466
37 + 139429 = 139466
43 + 139423 = 139466
73 + 139393 = 139466
79 + 139387 = 139466
97 + 139369 = 139466
127 + 139339 = 139466
157 + 139309 = 139466

Showing the first eight; more decompositions exist.
