Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469752, here are decompositions:

11 + 31469741 = 31469752
29 + 31469723 = 31469752
131 + 31469621 = 31469752
173 + 31469579 = 31469752
191 + 31469561 = 31469752
233 + 31469519 = 31469752
239 + 31469513 = 31469752
311 + 31469441 = 31469752

Showing the first eight; more decompositions exist.
