Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469452, here are decompositions:

5 + 31469447 = 31469452
11 + 31469441 = 31469452
29 + 31469423 = 31469452
41 + 31469411 = 31469452
149 + 31469303 = 31469452
173 + 31469279 = 31469452
383 + 31469069 = 31469452
419 + 31469033 = 31469452

Showing the first eight; more decompositions exist.
