Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469758, here are decompositions:

17 + 31469741 = 31469758
137 + 31469621 = 31469758
179 + 31469579 = 31469758
197 + 31469561 = 31469758
227 + 31469531 = 31469758
239 + 31469519 = 31469758
311 + 31469447 = 31469758
317 + 31469441 = 31469758

Showing the first eight; more decompositions exist.
