Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469616, here are decompositions:

29 + 31469587 = 31469616
37 + 31469579 = 31469616
47 + 31469569 = 31469616
53 + 31469563 = 31469616
89 + 31469527 = 31469616
97 + 31469519 = 31469616
103 + 31469513 = 31469616
149 + 31469467 = 31469616

Showing the first eight; more decompositions exist.
