Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469680, here are decompositions:

59 + 31469621 = 31469680
101 + 31469579 = 31469680
149 + 31469531 = 31469680
167 + 31469513 = 31469680
233 + 31469447 = 31469680
239 + 31469441 = 31469680
257 + 31469423 = 31469680
269 + 31469411 = 31469680

Showing the first eight; more decompositions exist.
