Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564196, here are decompositions:

67 + 31564129 = 31564196
229 + 31563967 = 31564196
379 + 31563817 = 31564196
409 + 31563787 = 31564196
463 + 31563733 = 31564196
733 + 31563463 = 31564196
919 + 31563277 = 31564196
1009 + 31563187 = 31564196

Showing the first eight; more decompositions exist.
