Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469800, here are decompositions:

3 + 31469797 = 31469800
17 + 31469783 = 31469800
59 + 31469741 = 31469800
179 + 31469621 = 31469800
239 + 31469561 = 31469800
269 + 31469531 = 31469800
281 + 31469519 = 31469800
353 + 31469447 = 31469800

Showing the first eight; more decompositions exist.
