Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471324, here are decompositions:

107 + 31471217 = 31471324
233 + 31471091 = 31471324
281 + 31471043 = 31471324
293 + 31471031 = 31471324
317 + 31471007 = 31471324
347 + 31470977 = 31471324
383 + 31470941 = 31471324
461 + 31470863 = 31471324

Showing the first eight; more decompositions exist.
