Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469700, here are decompositions:

11 + 31469689 = 31469700
29 + 31469671 = 31469700
47 + 31469653 = 31469700
71 + 31469629 = 31469700
79 + 31469621 = 31469700
113 + 31469587 = 31469700
131 + 31469569 = 31469700
137 + 31469563 = 31469700

Showing the first eight; more decompositions exist.
