Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469574, here are decompositions:

5 + 31469569 = 31469574
11 + 31469563 = 31469574
13 + 31469561 = 31469574
43 + 31469531 = 31469574
47 + 31469527 = 31469574
61 + 31469513 = 31469574
107 + 31469467 = 31469574
127 + 31469447 = 31469574

Showing the first eight; more decompositions exist.
