Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469234, here are decompositions:

37 + 31469197 = 31469234
103 + 31469131 = 31469234
193 + 31469041 = 31469234
241 + 31468993 = 31469234
271 + 31468963 = 31469234
331 + 31468903 = 31469234
373 + 31468861 = 31469234
457 + 31468777 = 31469234

Showing the first eight; more decompositions exist.
