Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469496, here are decompositions:

29 + 31469467 = 31469496
53 + 31469443 = 31469496
73 + 31469423 = 31469496
89 + 31469407 = 31469496
109 + 31469387 = 31469496
139 + 31469357 = 31469496
173 + 31469323 = 31469496
193 + 31469303 = 31469496

Showing the first eight; more decompositions exist.
