Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469462, here are decompositions:

19 + 31469443 = 31469462
109 + 31469353 = 31469462
139 + 31469323 = 31469462
163 + 31469299 = 31469462
223 + 31469239 = 31469462
331 + 31469131 = 31469462
421 + 31469041 = 31469462
499 + 31468963 = 31469462

Showing the first eight; more decompositions exist.
