Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139290, here are decompositions:

17 + 139273 = 139290
23 + 139267 = 139290
89 + 139201 = 139290
103 + 139187 = 139290
113 + 139177 = 139290
157 + 139133 = 139290
167 + 139123 = 139290
181 + 139109 = 139290

Showing the first eight; more decompositions exist.
