Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563346, here are decompositions:

137 + 31563209 = 31563346
197 + 31563149 = 31563346
257 + 31563089 = 31563346
317 + 31563029 = 31563346
359 + 31562987 = 31563346
569 + 31562777 = 31563346
719 + 31562627 = 31563346
743 + 31562603 = 31563346

Showing the first eight; more decompositions exist.
