Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469686, here are decompositions:

107 + 31469579 = 31469686
167 + 31469519 = 31469686
173 + 31469513 = 31469686
239 + 31469447 = 31469686
263 + 31469423 = 31469686
359 + 31469327 = 31469686
383 + 31469303 = 31469686
509 + 31469177 = 31469686

Showing the first eight; more decompositions exist.
