Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469372, here are decompositions:

19 + 31469353 = 31469372
73 + 31469299 = 31469372
79 + 31469293 = 31469372
163 + 31469209 = 31469372
229 + 31469143 = 31469372
241 + 31469131 = 31469372
271 + 31469101 = 31469372
331 + 31469041 = 31469372

Showing the first eight; more decompositions exist.
