Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479514, here are decompositions:

23 + 31479491 = 31479514
47 + 31479467 = 31479514
263 + 31479251 = 31479514
317 + 31479197 = 31479514
383 + 31479131 = 31479514
431 + 31479083 = 31479514
557 + 31478957 = 31479514
683 + 31478831 = 31479514

Showing the first eight; more decompositions exist.
