Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482556, here are decompositions:

5 + 31482551 = 31482556
47 + 31482509 = 31482556
167 + 31482389 = 31482556
263 + 31482293 = 31482556
383 + 31482173 = 31482556
389 + 31482167 = 31482556
467 + 31482089 = 31482556
509 + 31482047 = 31482556

Showing the first eight; more decompositions exist.
