Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469544, here are decompositions:

13 + 31469531 = 31469544
17 + 31469527 = 31469544
31 + 31469513 = 31469544
97 + 31469447 = 31469544
101 + 31469443 = 31469544
103 + 31469441 = 31469544
137 + 31469407 = 31469544
157 + 31469387 = 31469544

Showing the first eight; more decompositions exist.
