Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469932, here are decompositions:

29 + 31469903 = 31469932
71 + 31469861 = 31469932
83 + 31469849 = 31469932
149 + 31469783 = 31469932
191 + 31469741 = 31469932
311 + 31469621 = 31469932
353 + 31469579 = 31469932
401 + 31469531 = 31469932

Showing the first eight; more decompositions exist.
