Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469612, here are decompositions:

43 + 31469569 = 31469612
313 + 31469299 = 31469612
373 + 31469239 = 31469612
571 + 31469041 = 31469612
619 + 31468993 = 31469612
709 + 31468903 = 31469612
751 + 31468861 = 31469612
1039 + 31468573 = 31469612

Showing the first eight; more decompositions exist.
