Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464610, here are decompositions:

29 + 31464581 = 31464610
53 + 31464557 = 31464610
101 + 31464509 = 31464610
167 + 31464443 = 31464610
251 + 31464359 = 31464610
269 + 31464341 = 31464610
461 + 31464149 = 31464610
467 + 31464143 = 31464610

Showing the first eight; more decompositions exist.
