Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472948, here are decompositions:

31 + 2147472917 = 2147472948
151 + 2147472797 = 2147472948
191 + 2147472757 = 2147472948
197 + 2147472751 = 2147472948
251 + 2147472697 = 2147472948
331 + 2147472617 = 2147472948
337 + 2147472611 = 2147472948
347 + 2147472601 = 2147472948

Showing the first eight; more decompositions exist.
