Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483384, here are decompositions:

71 + 31483313 = 31483384
167 + 31483217 = 31483384
563 + 31482821 = 31483384
641 + 31482743 = 31483384
677 + 31482707 = 31483384
701 + 31482683 = 31483384
743 + 31482641 = 31483384
797 + 31482587 = 31483384

Showing the first eight; more decompositions exist.
