Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469560, here are decompositions:

29 + 31469531 = 31469560
41 + 31469519 = 31469560
47 + 31469513 = 31469560
113 + 31469447 = 31469560
137 + 31469423 = 31469560
149 + 31469411 = 31469560
173 + 31469387 = 31469560
233 + 31469327 = 31469560

Showing the first eight; more decompositions exist.
