Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534612, here are decompositions:

23 + 31534589 = 31534612
59 + 31534553 = 31534612
269 + 31534343 = 31534612
311 + 31534301 = 31534612
443 + 31534169 = 31534612
491 + 31534121 = 31534612
509 + 31534103 = 31534612
653 + 31533959 = 31534612

Showing the first eight; more decompositions exist.
