Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479466, here are decompositions:

47 + 31479419 = 31479466
167 + 31479299 = 31479466
197 + 31479269 = 31479466
269 + 31479197 = 31479466
383 + 31479083 = 31479466
449 + 31479017 = 31479466
509 + 31478957 = 31479466
659 + 31478807 = 31479466

Showing the first eight; more decompositions exist.
