Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469292, here are decompositions:

5 + 31469287 = 31469292
13 + 31469279 = 31469292
53 + 31469239 = 31469292
83 + 31469209 = 31469292
149 + 31469143 = 31469292
191 + 31469101 = 31469292
223 + 31469069 = 31469292
251 + 31469041 = 31469292

Showing the first eight; more decompositions exist.
