Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472376, here are decompositions:

17 + 31472359 = 31472376
37 + 31472339 = 31472376
83 + 31472293 = 31472376
137 + 31472239 = 31472376
167 + 31472209 = 31472376
193 + 31472183 = 31472376
197 + 31472179 = 31472376
223 + 31472153 = 31472376

Showing the first eight; more decompositions exist.
