Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469804, here are decompositions:

7 + 31469797 = 31469804
43 + 31469761 = 31469804
73 + 31469731 = 31469804
151 + 31469653 = 31469804
181 + 31469623 = 31469804
241 + 31469563 = 31469804
277 + 31469527 = 31469804
337 + 31469467 = 31469804

Showing the first eight; more decompositions exist.
