Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469504, here are decompositions:

37 + 31469467 = 31469504
61 + 31469443 = 31469504
97 + 31469407 = 31469504
151 + 31469353 = 31469504
181 + 31469323 = 31469504
211 + 31469293 = 31469504
307 + 31469197 = 31469504
373 + 31469131 = 31469504

Showing the first eight; more decompositions exist.
