Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469812, here are decompositions:

29 + 31469783 = 31469812
71 + 31469741 = 31469812
89 + 31469723 = 31469812
191 + 31469621 = 31469812
233 + 31469579 = 31469812
251 + 31469561 = 31469812
281 + 31469531 = 31469812
293 + 31469519 = 31469812

Showing the first eight; more decompositions exist.
