Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139044, here are decompositions:

11 + 139033 = 139044
23 + 139021 = 139044
67 + 138977 = 139044
107 + 138937 = 139044
127 + 138917 = 139044
151 + 138893 = 139044
181 + 138863 = 139044
223 + 138821 = 139044

Showing the first eight; more decompositions exist.
