Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479766, here are decompositions:

23 + 31479743 = 31479766
29 + 31479737 = 31479766
47 + 31479719 = 31479766
173 + 31479593 = 31479766
347 + 31479419 = 31479766
467 + 31479299 = 31479766
569 + 31479197 = 31479766
683 + 31479083 = 31479766

Showing the first eight; more decompositions exist.
