Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447350, here are decompositions:

17 + 31447333 = 31447350
83 + 31447267 = 31447350
97 + 31447253 = 31447350
139 + 31447211 = 31447350
251 + 31447099 = 31447350
269 + 31447081 = 31447350
271 + 31447079 = 31447350
281 + 31447069 = 31447350

Showing the first eight; more decompositions exist.
