Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446698, here are decompositions:

271 + 31446427 = 31446698
331 + 31446367 = 31446698
337 + 31446361 = 31446698
457 + 31446241 = 31446698
487 + 31446211 = 31446698
601 + 31446097 = 31446698
631 + 31446067 = 31446698
739 + 31445959 = 31446698

Showing the first eight; more decompositions exist.
