Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447352, here are decompositions:

19 + 31447333 = 31447352
163 + 31447189 = 31447352
271 + 31447081 = 31447352
283 + 31447069 = 31447352
331 + 31447021 = 31447352
379 + 31446973 = 31447352
499 + 31446853 = 31447352
613 + 31446739 = 31447352

Showing the first eight; more decompositions exist.
