Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469834, here are decompositions:

37 + 31469797 = 31469834
73 + 31469761 = 31469834
103 + 31469731 = 31469834
163 + 31469671 = 31469834
181 + 31469653 = 31469834
211 + 31469623 = 31469834
271 + 31469563 = 31469834
307 + 31469527 = 31469834

Showing the first eight; more decompositions exist.
