Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446716, here are decompositions:

109 + 31446607 = 31446716
163 + 31446553 = 31446716
277 + 31446439 = 31446716
349 + 31446367 = 31446716
463 + 31446253 = 31446716
487 + 31446229 = 31446716
619 + 31446097 = 31446716
733 + 31445983 = 31446716

Showing the first eight; more decompositions exist.
