Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446692, here are decompositions:

3 + 31446689 = 31446692
139 + 31446553 = 31446692
331 + 31446361 = 31446692
439 + 31446253 = 31446692
463 + 31446229 = 31446692
631 + 31446061 = 31446692
661 + 31446031 = 31446692
709 + 31445983 = 31446692

Showing the first eight; more decompositions exist.
