Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446016, here are decompositions:

5 + 31446011 = 31446016
59 + 31445957 = 31446016
167 + 31445849 = 31446016
227 + 31445789 = 31446016
293 + 31445723 = 31446016
353 + 31445663 = 31446016
443 + 31445573 = 31446016
509 + 31445507 = 31446016

Showing the first eight; more decompositions exist.
