Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469644, here are decompositions:

23 + 31469621 = 31469644
83 + 31469561 = 31469644
113 + 31469531 = 31469644
131 + 31469513 = 31469644
197 + 31469447 = 31469644
233 + 31469411 = 31469644
257 + 31469387 = 31469644
317 + 31469327 = 31469644

Showing the first eight; more decompositions exist.
