Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452706, here are decompositions:

23 + 31452683 = 31452706
29 + 31452677 = 31452706
83 + 31452623 = 31452706
107 + 31452599 = 31452706
167 + 31452539 = 31452706
179 + 31452527 = 31452706
503 + 31452203 = 31452706
569 + 31452137 = 31452706

Showing the first eight; more decompositions exist.
