Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469112, here are decompositions:

11 + 31469101 = 31469112
43 + 31469069 = 31469112
71 + 31469041 = 31469112
79 + 31469033 = 31469112
149 + 31468963 = 31469112
193 + 31468919 = 31469112
211 + 31468901 = 31469112
251 + 31468861 = 31469112

Showing the first eight; more decompositions exist.
