Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139152, here are decompositions:

19 + 139133 = 139152
29 + 139123 = 139152
31 + 139121 = 139152
43 + 139109 = 139152
61 + 139091 = 139152
73 + 139079 = 139152
131 + 139021 = 139152
193 + 138959 = 139152

Showing the first eight; more decompositions exist.
