Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469350, here are decompositions:

23 + 31469327 = 31469350
47 + 31469303 = 31469350
71 + 31469279 = 31469350
173 + 31469177 = 31469350
281 + 31469069 = 31469350
317 + 31469033 = 31469350
383 + 31468967 = 31469350
431 + 31468919 = 31469350

Showing the first eight; more decompositions exist.
