Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469848, here are decompositions:

107 + 31469741 = 31469848
227 + 31469621 = 31469848
269 + 31469579 = 31469848
317 + 31469531 = 31469848
401 + 31469447 = 31469848
461 + 31469387 = 31469848
491 + 31469357 = 31469848
521 + 31469327 = 31469848

Showing the first eight; more decompositions exist.
