Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464544, here are decompositions:

101 + 31464443 = 31464544
263 + 31464281 = 31464544
311 + 31464233 = 31464544
401 + 31464143 = 31464544
647 + 31463897 = 31464544
653 + 31463891 = 31464544
701 + 31463843 = 31464544
827 + 31463717 = 31464544

Showing the first eight; more decompositions exist.
