Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469262, here are decompositions:

23 + 31469239 = 31469262
53 + 31469209 = 31469262
131 + 31469131 = 31469262
193 + 31469069 = 31469262
229 + 31469033 = 31469262
269 + 31468993 = 31469262
359 + 31468903 = 31469262
401 + 31468861 = 31469262

Showing the first eight; more decompositions exist.
