Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469876, here are decompositions:

19 + 31469857 = 31469876
79 + 31469797 = 31469876
223 + 31469653 = 31469876
307 + 31469569 = 31469876
313 + 31469563 = 31469876
349 + 31469527 = 31469876
409 + 31469467 = 31469876
433 + 31469443 = 31469876

Showing the first eight; more decompositions exist.
