Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469100, here are decompositions:

31 + 31469069 = 31469100
59 + 31469041 = 31469100
67 + 31469033 = 31469100
73 + 31469027 = 31469100
107 + 31468993 = 31469100
137 + 31468963 = 31469100
181 + 31468919 = 31469100
197 + 31468903 = 31469100

Showing the first eight; more decompositions exist.
