Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469708, here are decompositions:

19 + 31469689 = 31469708
37 + 31469671 = 31469708
79 + 31469629 = 31469708
139 + 31469569 = 31469708
181 + 31469527 = 31469708
241 + 31469467 = 31469708
409 + 31469299 = 31469708
421 + 31469287 = 31469708

Showing the first eight; more decompositions exist.
