Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469190, here are decompositions:

13 + 31469177 = 31469190
47 + 31469143 = 31469190
59 + 31469131 = 31469190
89 + 31469101 = 31469190
149 + 31469041 = 31469190
157 + 31469033 = 31469190
163 + 31469027 = 31469190
197 + 31468993 = 31469190

Showing the first eight; more decompositions exist.
