Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469124, here are decompositions:

23 + 31469101 = 31469124
83 + 31469041 = 31469124
97 + 31469027 = 31469124
131 + 31468993 = 31469124
157 + 31468967 = 31469124
223 + 31468901 = 31469124
263 + 31468861 = 31469124
331 + 31468793 = 31469124

Showing the first eight; more decompositions exist.
