Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469548, here are decompositions:

17 + 31469531 = 31469548
29 + 31469519 = 31469548
101 + 31469447 = 31469548
107 + 31469441 = 31469548
137 + 31469411 = 31469548
191 + 31469357 = 31469548
269 + 31469279 = 31469548
479 + 31469069 = 31469548

Showing the first eight; more decompositions exist.
