Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469088, here are decompositions:

19 + 31469069 = 31469088
47 + 31469041 = 31469088
61 + 31469027 = 31469088
227 + 31468861 = 31469088
239 + 31468849 = 31469088
311 + 31468777 = 31469088
331 + 31468757 = 31469088
389 + 31468699 = 31469088

Showing the first eight; more decompositions exist.
