Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469508, here are decompositions:

41 + 31469467 = 31469508
61 + 31469447 = 31469508
67 + 31469441 = 31469508
97 + 31469411 = 31469508
101 + 31469407 = 31469508
151 + 31469357 = 31469508
181 + 31469327 = 31469508
229 + 31469279 = 31469508

Showing the first eight; more decompositions exist.
