Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479484, here are decompositions:

17 + 31479467 = 31479484
233 + 31479251 = 31479484
353 + 31479131 = 31479484
383 + 31479101 = 31479484
401 + 31479083 = 31479484
467 + 31479017 = 31479484
653 + 31478831 = 31479484
677 + 31478807 = 31479484

Showing the first eight; more decompositions exist.
