Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469936, here are decompositions:

13 + 31469923 = 31469936
79 + 31469857 = 31469936
139 + 31469797 = 31469936
283 + 31469653 = 31469936
307 + 31469629 = 31469936
313 + 31469623 = 31469936
349 + 31469587 = 31469936
367 + 31469569 = 31469936

Showing the first eight; more decompositions exist.
