Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139260, here are decompositions:

19 + 139241 = 139260
59 + 139201 = 139260
61 + 139199 = 139260
73 + 139187 = 139260
83 + 139177 = 139260
127 + 139133 = 139260
137 + 139123 = 139260
139 + 139121 = 139260

Showing the first eight; more decompositions exist.
