Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564348, here are decompositions:

17 + 31564331 = 31564348
107 + 31564241 = 31564348
191 + 31564157 = 31564348
269 + 31564079 = 31564348
359 + 31563989 = 31564348
401 + 31563947 = 31564348
419 + 31563929 = 31564348
449 + 31563899 = 31564348

Showing the first eight; more decompositions exist.
