Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469580, here are decompositions:

11 + 31469569 = 31469580
17 + 31469563 = 31469580
19 + 31469561 = 31469580
53 + 31469527 = 31469580
61 + 31469519 = 31469580
67 + 31469513 = 31469580
113 + 31469467 = 31469580
137 + 31469443 = 31469580

Showing the first eight; more decompositions exist.
