Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469524, here are decompositions:

5 + 31469519 = 31469524
11 + 31469513 = 31469524
83 + 31469441 = 31469524
101 + 31469423 = 31469524
113 + 31469411 = 31469524
137 + 31469387 = 31469524
167 + 31469357 = 31469524
197 + 31469327 = 31469524

Showing the first eight; more decompositions exist.
