Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471276, here are decompositions:

59 + 31471217 = 31471276
167 + 31471109 = 31471276
197 + 31471079 = 31471276
233 + 31471043 = 31471276
269 + 31471007 = 31471276
359 + 31470917 = 31471276
443 + 31470833 = 31471276
449 + 31470827 = 31471276

Showing the first eight; more decompositions exist.
