Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469148, here are decompositions:

5 + 31469143 = 31469148
17 + 31469131 = 31469148
47 + 31469101 = 31469148
79 + 31469069 = 31469148
107 + 31469041 = 31469148
181 + 31468967 = 31469148
229 + 31468919 = 31469148
421 + 31468727 = 31469148

Showing the first eight; more decompositions exist.
