Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469716, here are decompositions:

137 + 31469579 = 31469716
197 + 31469519 = 31469716
269 + 31469447 = 31469716
293 + 31469423 = 31469716
359 + 31469357 = 31469716
389 + 31469327 = 31469716
647 + 31469069 = 31469716
683 + 31469033 = 31469716

Showing the first eight; more decompositions exist.
