Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469074, here are decompositions:

5 + 31469069 = 31469074
41 + 31469033 = 31469074
47 + 31469027 = 31469074
107 + 31468967 = 31469074
173 + 31468901 = 31469074
251 + 31468823 = 31469074
281 + 31468793 = 31469074
317 + 31468757 = 31469074

Showing the first eight; more decompositions exist.
