Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469554, here are decompositions:

23 + 31469531 = 31469554
41 + 31469513 = 31469554
107 + 31469447 = 31469554
113 + 31469441 = 31469554
131 + 31469423 = 31469554
167 + 31469387 = 31469554
197 + 31469357 = 31469554
227 + 31469327 = 31469554

Showing the first eight; more decompositions exist.
