Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469668, here are decompositions:

47 + 31469621 = 31469668
89 + 31469579 = 31469668
107 + 31469561 = 31469668
137 + 31469531 = 31469668
149 + 31469519 = 31469668
227 + 31469441 = 31469668
257 + 31469411 = 31469668
281 + 31469387 = 31469668

Showing the first eight; more decompositions exist.
