Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469320, here are decompositions:

17 + 31469303 = 31469320
41 + 31469279 = 31469320
251 + 31469069 = 31469320
293 + 31469027 = 31469320
353 + 31468967 = 31469320
401 + 31468919 = 31469320
419 + 31468901 = 31469320
563 + 31468757 = 31469320

Showing the first eight; more decompositions exist.
