Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447196, here are decompositions:

7 + 31447189 = 31447196
97 + 31447099 = 31447196
127 + 31447069 = 31447196
199 + 31446997 = 31447196
223 + 31446973 = 31447196
337 + 31446859 = 31447196
349 + 31446847 = 31447196
439 + 31446757 = 31447196

Showing the first eight; more decompositions exist.
