Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464436, here are decompositions:

167 + 31464269 = 31464436
293 + 31464143 = 31464436
389 + 31464047 = 31464436
557 + 31463879 = 31464436
587 + 31463849 = 31464436
593 + 31463843 = 31464436
677 + 31463759 = 31464436
719 + 31463717 = 31464436

Showing the first eight; more decompositions exist.
