Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559262, here are decompositions:

11 + 31559251 = 31559262
23 + 31559239 = 31559262
43 + 31559219 = 31559262
73 + 31559189 = 31559262
101 + 31559161 = 31559262
113 + 31559149 = 31559262
131 + 31559131 = 31559262
181 + 31559081 = 31559262

Showing the first eight; more decompositions exist.
