Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469518, here are decompositions:

5 + 31469513 = 31469518
71 + 31469447 = 31469518
107 + 31469411 = 31469518
131 + 31469387 = 31469518
191 + 31469327 = 31469518
239 + 31469279 = 31469518
449 + 31469069 = 31469518
491 + 31469027 = 31469518

Showing the first eight; more decompositions exist.
