Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469608, here are decompositions:

29 + 31469579 = 31469608
47 + 31469561 = 31469608
89 + 31469519 = 31469608
167 + 31469441 = 31469608
197 + 31469411 = 31469608
251 + 31469357 = 31469608
281 + 31469327 = 31469608
431 + 31469177 = 31469608

Showing the first eight; more decompositions exist.
