Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469130, here are decompositions:

29 + 31469101 = 31469130
61 + 31469069 = 31469130
89 + 31469041 = 31469130
97 + 31469033 = 31469130
103 + 31469027 = 31469130
137 + 31468993 = 31469130
163 + 31468967 = 31469130
167 + 31468963 = 31469130

Showing the first eight; more decompositions exist.
